Question

If my 6 year old has a pacifier in his mouth and diapered all the time is it normal?

Answer 1

It is perfectly normal and okay if your 6 year old has a pacifier in his mouth and is diapered all the time.

If he enjoys wearing his diapers and using his pacifier he should continue doing so.
