Question
My friend’s baby has already learned to use a walker at six months old, but my baby still can’t sit properly, and there are no teeth coming in. What’s going on? I’m a bit worried. What are the standard developments for a six-month-old baby?
Answer
Normally, children develop the cervical physiological curvature around three months old, at which time neck movement can be observed. By six months, the baby will develop the thoracic physiological curvature, allowing for independent sitting and rolling over. Around twelve months, the lumbar physiological curvature begins to form, enabling the child to stand and walk alone. Therefore, a six-month-old baby generally can sit independently and may have teeth emerging, but is not yet capable of learning to stand and walk. Based on this, your baby’s development appears to be normal.
