A member asked:

When do babies get necks, my daughter has a double chin and no neck?

A doctor has provided 1 answer

Over time: Most women would agree that adding the length of a neck to a newborn would be a bit too much to fit. Infants do grow about an inch in their neck in the first 9 months which reduces the chin fold and allows them more room to mouth breathe when they get stuffy.
