Walk In Pediatrician My 16 Month Old Is Not Walking?

My 16 month old is not walking? - walk in pediatrician

I have a daughter 16 months is not running. His pediatrician said it was the end of the evening occurs when (March 15-18 months. Late) What is worrisome is the amount to rotate the feet and foot is now fully on his knees. It is roughly 30 pounds, they say that it is not good for the development of the muscles.

She starts physical therapy next week with the PT and the nurse came to my house.

Does anyone have any experience with the foot a little too late, or experience with the PT with an infant?
