Babies and sitting: When do babies sit up
Most babies begin to sit up around their 6 month “birthday,” an exciting time indeed. Not only is sitting up a significant milestone parents look forward to, but it is also often a sign your baby may soon be ready for solids! While some babies can begin to sit as early as the age of 4 months, most babies will master the skill of sitting on their own in their 6th month of life. Your baby sitting up is definitely something to celebrate because it opens up an entirely new world of exploration and discovery for your little one.

Signs your baby may be ready to sit
One of the first signs your baby is ready to sit up on their own is being able to sit in a tripod position with both legs extended and one arm steadying them. Another sign your baby may be ready to sit up unassisted soon is observing them sit upright (without support) for a few seconds at a time.
What you can do to help your baby to sit
There are several ways to encourage your baby to practice their sitting skills. Keep in mind that sitting takes a strong core and balance which you can foster from an early age. Here are 3 ways you can help your baby learn to sit up:
Tummy time is a great activity you can begin doing with your baby from an early age to help them build the strength needed to hold their head up without support and eventually sit. The American Academy of Pediatrics (AAP) encourages starting tummy time from birth. In the very early weeks, you may find it difficult to incorporate tummy time into your day-to-day activities which is understandable since newborns feed and sleep A LOT! Once you begin tummy time, be sure to spend at least 15 minutes a day engaging with your baby on the floor while they practice lifting and turning their head.
Pro tip: You do not have to do tummy time for 15 minutes straight; if your baby is not the biggest fan of being on their belly, try breaking up the activity into (3) 5-minute blocks.
Assist your baby in sitting up
Once your baby is at least 3 months old and has had plenty of practice with tummy time, the next step is to encourage your child to lift their body up from a lying position. Think of this exercise as assisted crunches. As your baby lies on their back, sit opposite of them and extend your arms out. With your hands interlocked, gently assist your baby in sitting up. Repeat 5 - 10 times. This exercise helps build core strength and may be really fun for babies!
Engage baby with toys
Holding up interesting toys or books is another fun and helpful activity you can do with your baby to encourage independent sitting. Age-appropriate toys for 4 - 8 month olds include musical instruments, soft balls, unbreakable mirrors, noisy teething balls, and security blankets.
What should I do if my baby is sitting up instead of sleeping?
New sitters can sometimes be so excited about their new skill that they will sit up in their sleep space when they should be sleeping. Although it can be cute to see your baby sitting in their sleep space you may begin to wonder if they will ever fall asleep! Our general recommendation is to avoid repositioning your baby too frequently. If your baby is happy try to give them at least 5 - 10 minutes before attempting to lay them down again. Sometimes babies simply are not tired yet and will lay down on their own once they feel more drowsy. Repositioning your baby too often can feel frustrating for you and be overly stimulating for your baby. If your baby continues to sit right back up after attempts to lie down, consider getting your baby up for a short break before doing a shortened version of your sleep routine and trying again.
Q: When do babies start sitting on their own?
Although it’s less common, some babies will begin sitting unassisted as early as 4 months. Most babies will be able to sit up on their own at around 6 months. A few babies may need a little extra time and begin sitting up closer to 8 or 9 months. It is important not to rush this milestone; just like every other milestone, your new baby will master it, and every baby will reach this milestone at their own pace.
Q: When do I start sitting my baby up?
You can begin practicing sitting up with your baby as early as 4 months. If your baby still seems pretty unstable sitting up, focus on tummy time and assisted “crunches” until they show signs of readiness.
Q: Can my baby use a baby seat?
Props and seats designed to assist a baby in sitting can actually delay your baby’s development. Rather than relying on infant positioners or seats (e.g., the Bumbo seat), pediatric physical therapists recommend allowing babies to work on this skill independently. Avoiding the aid of assisted sitting devices will ensure your child develops a strong core and is confident sitting on their own.
Q: Does sitting position affect baby?
Once your baby is the appropriate age to begin practicing sitting on their own, sitting upright (for a few minutes at a time) will prepare them for their next big motor skills including pulling up, cruising, and eventually WALKING!
Q: Is it normal for a baby to throw himself backward when sitting?
Sometimes babies will fatigue while attempting to sit up on their own for longer periods of time; when this happens you may notice your baby leans or throws themselves backward. To prevent injury, be sure to sit within arm's reach of your baby and assist them in sitting back up again if you see they’re losing their balance. This is also a sign your baby is in need of a break from sitting up and is ready for another activity.
Q: Is holding your baby in a sitting position bad?
Holding your baby in a sitting position is a great way to help your baby build confidence and master sitting on their own. It is often helpful to sit a few inches behind your baby with your legs extended around your baby in case they need a quick reset. Alternatively, you can practice sitting the baby in front of you with your hands extended out to catch them if they wobble. If this is your first time sitting a baby on their own, consider “side sitting baby” with one leg in front and one leg behind your baby to help them balance.
