How old is the baby before he can sit up by himself?

Parents are very worried about their children's physical development during the process of raising them. Once the child is slightly uncomfortable or has a seizure, parents begin to worry. They are even worried about whether the child's intellectual development is abnormal. If the baby is too young, then he will definitely not be able to sit up by himself. Many people think that the earlier the baby can sit up, the better the child's physical development will be. However, the baby must reach a certain age before he can sit up. So how old is the baby to sit up by himself?

Development status: When the baby is 6 or 7 months old, the spine, back and waist have gradually grown stronger, so turning over to sitting up is a natural development of continuous movements; usually the baby will first lean on a semi-reclining position, then the body will slightly lean forward and use both hands to assist in support on both sides.

Generally speaking, babies will start to learn to sit independently between 6 to 6 and a half months old. However, if they fall over, they will not be able to sit up again on their own. It will take until they are 8 to 9 months old before they can sit well without any help.

What being able to sit means: If your baby can sit steadily, it means his bone development, nervous system, muscle coordination ability, etc. are gradually maturing. Of course, the baby's muscle development is gradually stabilizing at this time.

Regarding bones:

When the baby learns to sit, parents should pay special attention to not letting the baby sit for too long, because the baby's spine is not fully developed at this stage. If the baby is allowed to sit for a long time, it is easy to cause the spine to not fully develop. If the baby is allowed to sit for a long time, it is easy to cause scoliosis and damage growth and development.

Reminder: Do not let your baby kneel with his legs forming a "W" shape or press his legs under his buttocks, as this will easily affect the future development of his legs. The best posture is to sit cross-legged with his legs crossed and facing forward.

In addition, some babies may have a protruding back when sitting, which may mean that the baby is too thin; but if you find abnormal skin color on the protruding back, you must pay attention.

How old can a baby sit up by himself? Through the above introduction, I believe many people have understood the relevant knowledge. Babies can sit up by themselves when the time comes, so parents don’t need to worry. If the child exceeds the normal sitting time, you can take the child to the hospital for a check-up to see if there are any abnormalities in the child’s development, and then provide symptomatic treatment.
