If you’re curious about your baby’s growth, check out these guides to your baby’s 52-week growth spurt. Don’t worry if your baby doesn’t grow exactly as described in the baby milestone chart; every child grows in a unique way. Discuss questions and concerns with your pediatrician often.
Week 1: It’s only been a week, but your newborn already knows she can count on you. She can now recognize your voice, and this familiarity helps her adjust to the strange new world outside the womb. She won’t understand you, but talk to her often to show love and comfort.
Week 2: During your baby’s second week of life, he can focus on objects 8 to 14 inches away, the distance between his eyes and yours during nursing. As you feed your little one, slowly move your head from side to side to see if his eyes follow you. This will help develop his eye muscles and tracking skills.
Week 3: Although her movements are still random and jerky, by week 3 your baby will be ready to start snuggling up to you. As you hold her, notice how she adjusts her position to you. She finds that your arms and even your scent can be calming and comforting.
Week 4: Have you noticed that your baby uses his vocal cords in addition to crying? This week he may be cooing and making “ahh” sounds, especially when he sees mommy and daddy. Babies learn by imitation, so repeat his sounds to him.
1 Month Baby Milestones
Week 5: This week, your baby’s movements become smoother and more purposeful, and those random jerky movements begin to disappear. Set aside some time each day to use her body ー for example, you can slowly pull her into a sitting position to give her a little gentle exercise, or let her rest on your forearm and let her “fly”. Always support your head during the movement.
Week 6: At this age, your baby will have a delightful grin, his first genuine smile. How do you know? His eyes will brighten and widen as he opens his mouth upward.
Week 7: Your baby is beginning to understand her senses; she can look at the rattle and associate it with the sounds it makes. She also begins to favor colors, preferring bright shades and three-dimensional objects to flat black and white.
Week 8: While your little one’s head is still bobbing, the muscles in her neck are getting stronger by the day. In fact, your baby may be able to hold his head up 45 degrees. Have him practice on his back for short periods of time each day so he can practice.
2 Months Baby Milestones
Week 9: Sounds fascinate your baby, especially high and high pitched sounds. She is also interested in hearing you talk and will stare intently at your mouth when you talk to her. She may even respond with a coo or “coo”.
Week 10: Around week 10, your baby can recognize his parents’ faces in a group of people. His eyes may widen and he may squirm gleefully when a familiar person approaches. He’s ready to hone his social skills, so let her participate in family activitiesーーfor example, bringing him to the table at dinner or putting him in a sling while you work.
Week 11: Your baby is staying awake longer now. She is eager to learn about her world, and she may not always be interested in your play choices. If she turns her head to look somewhere else, she is announcing that she is ready to do something else.
Week 12: At this age, your baby has discovered an endless source of magic: his hands. He realizes that these fingers and thumbs are separate objects. He can also put his hands together, look at them, and put them in his mouth to taste them. Let him try these wonderful tools that offer different textures for him to feel, such as a velvet scarf or a rubber toy.
3 Months Baby Milestones
Week 13: In addition to giving you sweet smiles and cooing sounds, your baby may laugh, giggle, and teethe on a long chain.
Week 14: Rattles and toys that wiggle around not only entertain your 14-week-old, but also develop your baby’s hand and eye skills. She is also attracted to multi-textured toys, bright primary colors, and things that make sounds. She will pat or grab them (and she will try to put them in her mouth!)
Week 15: Say goodbye to a relatively still baby. Around week 15, your little one may begin to rollーーfrom back to front or front to back. Over the next few weeks, he may be able to control his rolling in one direction. For safety reasons, make sure he is not left alone in his bed or high up.
Week 16: Your little one is getting stronger every day. She may protest when she is placed on her tummy, but she needs tummy time every day to work the muscles in her neck, chest, thorax and arms. These muscle groups are necessary to roll, sit up, and crawl. Sit on the floor with her and talk out of her field of vision. While she’s busy looking for you, she’ll be distracted by the fuss for a few minutes!
4 Month Infant Milestones
Week 17: Your baby may entertain everyone (including himself) by making mocking noises or blowing raspberries. He will laugh when you tickle his tummy, and he will mimic your words by making similar sounds. Whenever possible, talking and making eye contact with him will improve his self-awareness and presentation skills.
Week 18: You may find your baby playing alone in a like-by-like manner. Her eyesight is now sharp and her depth perception is improving. She is very busy using her eyes and hands to play to learn about herself.
Week 19: Your child’s father claims he hears “daa daa” clearly, but at 19 weeks old, your baby doesn’t know what these sounds mean; he simply puts consonants and vowels together. You can help him associate sounds with meaning by labeling things: point to pictures in books and touch their eyes, noses and mouths as you name them. Soon, he’ll be calling you by your first names!
Week 20: By now, your baby knows exactly who you are and is even beginning to understand herself. When she sees her image in the mirror, she smiles and begins to show some distinct personality traits. By looking at her face, you may also be able to discover how she expresses different emotions.
5 Months Baby Milestones
Week 21: Your baby is five months old. He may be crawling around on the floor and turning around to see new sights. Put him on the floor or in a baby enclosure and let him entertain himself (of course, keep a close eye on his movements)
Week 22: This week, baby’s favorite experiment was putting everything in his mouth. He also performed some new tests, such as throwing toys on the floor and comparing the different sounds they make.
Week 23: Your baby is developing muscle coordination from the head down. By 23 weeks, she may have gained strength in her upper body, but her legs and trunk are ready for the challenge. There are ways to help her progress: gently pull her into a standing position on your lap and bounce her, or pull her into a sitting position on the floor.
Week 24: This week your baby is beginning to store memories. He recognizes names, basic words like “no” and “goodbye”, and familiar sounds. He will look at you when you point to objects and point to them when you name them.
6 Month Infant Milestones
Week 25: In the next few months, some of the major accomplishments that babies make – sitting, crawling, walking – occur with widely varying frequency. Your baby may be more stable when trying to sit, but may still need help. Support her with a few pillows to prevent falls.
Week 26: Your baby is still charming, but he may smile more selectively at strangers. He may even be afraid to leave you. To reduce his anxiety and make your separation less sad, try leaving right after feeding. Stick to your schedule and establish a “goodbye” routine to give him a sense of security.
Week 27: You may have noticed your baby dropping something on the floor. This action teaches her about cause and effect. When she gets the response she expects, it reinforces her understanding of how the world works.
Week 28: By week 28, your baby is using his hands in more complex waysーhe may begin to clap or imitate you when you wipe his food dish. He may also be ready to start feeding himself, so prepare some finger-soft food for him (make sure they’re not a choking hazard).
7 Months Baby Milestones
Week 29: Although she’s not ready to host a dinner party, your baby is eager for some more sophisticated ways to socialize. She enjoys peek-a-boo and other group games.
Week 30: If he hasn’t started crawling yet, your baby is busy mastering the muscle coordination and strength needed for this movement. His first attempt may be to “crawl” (push himself on his belly). Next, he can push upward on his hands, knees and rocks. Give him plenty of time to practice and give him plenty of encouragement.
Week 31: Your baby’s hands may have evolved from small claws to small tools. Instead of clumsily grasping things, he is learning how to manipulate his thumb and index finger to pick up and hold objects. This “pincer grasp” will develop more in the coming weeks. Be extra vigilant not to let his curious fingers come in contact with choking hazards on the floor.
Week 32: Although still young, your baby can lean freely on furniture. Soften her falls by placing them under a rug or blanket.
8 Months Infant Milestones
Week 33: Your little man now has a mind of his own, and he’s sure to let you know what he likes and dislikes. While this may be unsettling, remember that he is experimenting with his emotions and learning how to control his environment.
Week 34: Over the past few weeks, your baby’s leg and foot coordination and strength have improved. She may have finally found out how to stand up. Encourage her to stand up by placing her favorite toy on a sturdy chair. Point to the chair, tell her the toy is there, and cheer for her to get up and grab it.
Week 35: Your baby strings syllables together and puts different consonants and vowels together. She may understand common words like “ball” and “bottle.” To satisfy her thirst for knowledge, read her many baby books and make labels for her. She is taking in every word!
Week 36: At about 8 to 9 months of age, the baby can create memories from his experiences. He may look at a ball, remember how it moves, and then push it. He may even set goals for himself, such as crawling to a pot to make a noise and then hitting it with a spoon.
9-Month Infant Milestones
Week 37: If you haven’t already, look around the house and put dangerous things out of your child’s reach. Her curiosity is boundless, and her flexibility allows her to go farther and faster.
Week 38: At about 38 weeks, your baby will be leaving a trail of where he’s been. As he wanders around the house, he may take books off the shelves and clean the inside out of the cupboards. He will also be happy to tip over the wastepaper basket. While it is exhausting to keep cleaning up his mess, this curiosity is a natural part of his development.
Week 39: If you think your baby is always stuffing things in her mouth, you’re probably right. 8- to 12-month-olds spend at least 20 percent of their waking hours playing, rolling over, or banging on small objects.
Week 40: Your baby will watch you intently as you go about the seemingly mundane tasks of the day. He’s beginning to imitate you, too. If given the opportunity, he may bring a toothbrush and brush over his teeth or try to comb his hair. Imitation is an important way for your baby to learn.
10 Months Baby Milestones
Week 41: At your baby’s insistence, you may have spent three nights rereading Goodnight, Moon. She is comfortable focusing on each page, seeing the same pictures, and hearing the same words over and over again. Don’t deny her requests; it’s building her self-esteem.
Week 42: Your baby is constantly discovering new and faster ways to move. He is likely to cruise around while holding furniture and may even take a few steps without assistance. The longer he practices using his legs, the stronger he will become and the better his physical coordination will be.
Week 43: Out of sight, out of mindーーYour baby now knows that objects exist, even if she can’t see them. She will look under the blanket for a book she misplaced or play a game where she throws a toy into a container and turns it upside down. You can reinforce the concept of object permanence by playing a simple game of hide-and-seek. Hide a toy under a cup and let her find it.
Week 44: Your baby has discovered that his world is not just about what he sees on the ground. The lure of stairs and furniture is irresistible, so be sure to install safety gates.
11 Months Infant Milestones
Week 45: By now, your baby prefers to feed herself and may even take the spoon out of your hand at mealtime. This practice helps her master fine motor skills.
Week 46: Your baby’s personality is really blossoming now. She is forming her own opinions and is not shy about expressing her preferences for people and activities. If diaper changes turn into wrestling matches, remember that she is demonstrating her newfound independenceーーthis is a positive step in the developmental process.
Week 47: To reduce accidents with your increasingly mobile baby, make state laws. While learning through exploration is important for him, he also needs some limits and boundaries. Demonstrate this by giving him simple instructions: Let’s walk to the sidewalk and stop.
Week 48: Your baby may or may not be walking, but she is definitely making an effort to get around. She’s wandering around the furniture, holding your hand as she walks, and may not even want to sit down. This is an important milestone, although babies may be taking their first steps independently anywhere from 8 to 15 months. You can help her walking skills by giving her a sturdy push and pull toy and placing furniture in strategic areas to encourage her to cruise.
12-Month Infant Milestones
Week 49: There is another side to your baby’s newly acquired independence: insecurity. She realizes that by doing things on her own, she is a separate entity from you. Her anxiety around strangers may also return. Be near her when she needs you, reassure her, and give her attention when she asks you for help.
Week 50: At the end of the day, you may be ready to crash, but your baby is too excited about her new accomplishment to sleep. During her last feeding, hold her in your arms in a dark room and rock her gently while singing. By establishing a relaxed bedtime routine, she will soon look forward to and appreciate a break from a stressful day.
Week 51: Your baby is learning how much he can handle. He finds himself
