10-Week-Old Babies: What to Expect


10-Week Old Baby Milestones

At 10 weeks, your baby has made it past their second month of life and is fast approaching their third. This is an exciting period for many parents, as 10 weeks is typically when mothers begin to feel like they’ve found a nice rhythm with their newborns and can start to resume their pre-baby lives. This means going back to work or resuming old hobbies; you may even be taking your 10 week old baby to daycare or leaving them with a nanny as you head back to the office.

Here is a complete guide to your baby’s 10th week of life. This will help you prepare for new milestones, regulate their sleep schedule and incorporate some new activities that can help you bond.


A 10 week old baby is starting to become more alert and responsive to others. They’re officially in the double digits, and you may start saying that your child is “two months” or “almost three months” old instead of counting the weeks on your fingers.

Growth Spurt

Many 10-week-olds go through a growth spurt that has parents frantically pulling out the onesies and tiny pants they thought they wouldn’t need for months to come. This is the stage where arms and legs may be extra chubby, and it will be hard to resist pinching their little thighs.

You’ll most likely be able to start packing away the newborn clothes as your 10-week-old begins to outgrow them. Swings, bouncy chairs, strollers and car seats will also need their straps adjusted to accommodate your growing baby.

Better Hand-Eye Coordination

Babies are legally blind at birth, and their vision continues to rapidly develop during the first several months of life beyond the womb. Around 10 weeks, babies begin to see things a bit more clearly and might start to associate objects with their visual input.

At first, they may reach for something they’re looking at without realizing it. Over time, they will begin to notice things more and reach for them, so your hair, earrings or glasses could become their favorite new discovery.

A 10 week old baby still can’t grasp things, but their hand-eye coordination is beginning to develop. This is an important milestone that will help them piece together the world around them as they grow and gain greater mobility.

More Deliberate Movement

A 10 week old baby can lift its head and hold it for a few seconds at a time. Their neck muscles are developing, so they will begin to hold their heads up more often. If your baby does not use its neck muscles at all by 10 weeks, talk to your pediatrician. They may recommend you try some tummy time.

If you hold your baby upright, you may notice that they’ve begun to place more weight on their legs. You should do this when you are on a soft surface, preferably on the ground. You may find that they can support themselves for a brief instant. Although they’re a long ways off from crawling, this moment can have you feeling like they’ll be walking in no time!

Greater Reactions

Your 10-week-old will start to respond differently to music and other sounds. If you play different lullabies, you may notice that they become more alert and engaged with some more than others. If they haven’t already, your baby may also start to smile on purpose.

Eating Habits

To accommodate their growth sport, 10-week-olds may need to eat bigger meals. Babies at this stage need approximately five to six feedings throughout the day, but this may vary depending on your child.

A 10 week old baby’s feeding schedule might occur every three hours or so. Now, your baby will make a sucking motion when they’re hungry, so you’ll definitely know when they haven’t had enough to eat.

Some 10-week-olds will eat smaller amounts throughout the day while others prefer shorter, larger feedings. It all depends on your baby, and you’ll both be discovering your rhythm together at this stage.

At 10 weeks, pay attention to your baby’s cues. If he or she cries and wants more milk, give it to them. If they are not hungry, they may knock the bottle out of your hand or stop suckling.

Sometimes, babies aren’t as hungry as usual, so they may not finish their regular feeding. This does not indicate illness or a major health issue if it happens every so often, but if your 10 week old baby refuses feedings or stops eating much altogether, you should make an immediate appointment with your pediatrician.

Sleep Schedule

Some babies start to sleep through the night as early as six weeks of age. Your baby may still be suffering from colic, so if your little one hasn’t stopped crying or learned to sleep through the night yet, it should ease up shortly.

A 10 week old baby sleeps between 14 to 17 hours every day, so you will have plenty of naps between feedings. Naps will last several hours at a time, and you can use them as a good opportunity to practice sleep training.

Your 10-week-old should start to fall into a more stable sleep schedule at this age, waking less frequently throughout the night. Whether or not they wake up a few times, most parents of a 10 week old baby are delighted to enjoy some more uninterrupted sleep.

Size and Growth

Babies go through several growth spurts throughout their first year, and the 10-week mark is one of the most noticeable for many parents. Your baby can gain up to 3 pounds and grow between 2 to 3 inches taller. They will definitely feel more like a “real baby” than a newborn at this stage, and they may have some more hair as well as more expressive eyes and facial features.

Breastfed babies typically weigh more at 10 weeks than formula-fed ones, but the average 10 week old baby weighs 10 to 12 pounds.

A 10 week old baby can have up to 15 diapers a day and four to five bowel movements. Baby poop looks very different from adults, which can be a big surprise for first-time parents. At 10 weeks, breastfed babies will have yellowish-green bowel movements with noticeable flecks. Those who consume a formula-based diet will have a more pasty, light-brown colored poop with a creamy consistency.


A 10 week old baby is becoming more alert and responsive when it’s awake. Tummy time at 10 weeks should happen at least two to three times a day for 10 to 15 minutes each. Many babies scream as soon as they’re put in position, so work your way up slowly and help your baby adjust to longer periods.

You should never leave a 10 week old baby on its stomach or with its face down. Your baby’s neck muscles may not be strong enough to support the weight of its head yet, so you should only do tummy time as long as your baby is comfortably able to do so.

Music and soft toys are also fun activities to help you bond with your baby. Lullabies are a good way to help stimulate your baby’s mind, and many colorful, crinkly toys will keep their attention.

  1. My baby never slept well (especially through the night) until I started using the website – that website has been by far one of the best things I’ve ever got my hands on to get him to fall asleep quickly. Best time is 45 seconds from awake to asleep! Can’t imagine life without it! I heard about it through a kindergarten teacher who uses it to put to sleep a group of 30 children. Check it out! SLEEPBABY.ORG 🙂 Best of luck to you and your family!

  2. If your baby won’t sleep, check out the sleep method from – Thank you SleepBaby for this brilliant method! My daughter now sleeps from 7pm to 6 or 6:30am every night with almost no night wakings. And even if she wakes, it’s usually just for a second and then she falls back asleep all on her own.

    Most nights I get my 8 hours of sleep and it’s just wonderful! I really feel like I understand her little body and mind and can address her sleeping holistically. I can’t thank you enough, Kacey and the team!

  3. Our son now sleeps through the night because of!

    Our baby had trouble sleeping through the night from the time we brought him home from the hospital. We tried changing his formula and even putting his crib in our bedroom. Nothing I tried before SleepBaby worked. The night after I started using, he started sleeping for several hours at a time.

    I really enjoyed the tips on how to make my baby laugh. I love hearing him laugh and I think SleepBaby’s laughter tips help relax him so it’s easier for him to sleep. Oh! And I also liked the instructions about how to create the right environment in his room that’s relaxing.
