Patient's question:
A friend's baby has already been able to sit in a walker at six months, but mine still can't sit properly, and their teeth haven't come in yet. What's going on? I'm a bit worried. What are the developmental milestones for a six-month-old baby?Doctor's answer:
Under normal circumstances, children form their cervical physiological curves around three months of age, at which point neck movement can appear. At six months, the thoracic physiological curve develops, and the child can sit and stand independently, as well as roll over. Around twelve months, the lumbar physiological curve begins to form, and the child can stand and walk independently. Therefore, at six months, most children can sit independently, though they may be teething, but they cannot yet learn to stand or walk. Currently, the child's development appears to be normal.
