when can babies sit up

When can babies sit up on their own?

Babies must be able to hold their heads up without support and have enough upper body strength before being able to sit up on their own. Babies often can hold their heads up around 2 months, and begin to push up with their arms while lying on their stomachs.

At 4 months, a baby typically can hold his/her head steady without support, and at 6 months, he/she begins to sit with a little help. At 9 months he/she sits well without support, and gets in and out of a sitting position but may require help. At 12 months, he/she gets into the sitting position without help.

Tummy time helps strengthen the upper body and neck muscles that your baby needs to sit up. Around 6 months, encourage sitting up by helping your baby to sit or support him/her with pillows to allow him/her to look around.

When to see a doctor

Babies develop at a different rate. At 5 months, talk to your doctor if your baby:

  • doesn’t seem interested in things around them
  • doesn’t seem to know you
  • isn’t making any voice sounds
  • doesn’t open their fingers
  • doesn’t kick their legs, or their legs are bent most of the time
  • doesn’t follow an object with their eyes or make eye contact
  • doesn’t turn when you speak to them, or they aren’t startled by a loud noise
  • is unhappy or unsettled most of the time

When do babies roll over?

Babies start rolling over as early as 4 months old. They will rock from side to side, a motion that is the foundation for rolling over. They may also roll over from tummy to back. At 6 months old, babies will typically roll over in both directions. It’s common for babies to roll over from tummy to back for a month or two before rolling over from their back to front.

To encourage rolling over, place your baby on a blanket on the floor with a toy or book to one side near him/her to reach toward with her arms.

When do babies crawl?

At 6 months old, babies will rock back and forth on hands and knees. This is a building block to crawling. As the child rocks, he may start to crawl backward before moving forward. By 9 months old, babies typically creep and crawl. Some babies do a commando-type crawl, pulling themselves along the floor by their arms.

To encourage a child’s crawling development, allow your baby to play on the floor in a safe area away from stairs. Place favorite toys just out of reach as the baby is rocking back and forth. Encourage him/her to reach for his/her toy.

As your baby becomes more mobile, it’s important to childproof your home. Lock up household cleaning, laundry, lawn care and car care products. Use safety gates and lock doors to outside and the basement.
