Dr Jill, my son is six months old and he's not crawling yet, is that normal?
gpt
That's completely fine and no reason to worry at all! Babies usually don't start fully crawling until seven months old, and it's not abnormal for it to be even later than that.
human
What milestones should he have reached at six months?
gpt
He should be able to roll from front to back and back to front, sit with support, bear weight on his legs when he is held upright, recognize familiar people and objects, smile, laugh and show affection, among other things.
