Child turned 14months, but not able to walk unassisted.

My daughter currently is 16 months, and she was only manage to start walking independently in late 15 months, no worry, no hurry, they have their own time, they will walk when they are ready! I didn't worry about it at all even a lot of stranger in the playground told me your daughter should see doctor, u should don't hold her, let her fall down. But u know, I love my girl hold my hand, and I am willing to let her hold it forever. Or whenever she is ready, and I will let go. don't worry too much ok! enjoy the moment that he still holding your hand.
