My toddler is a very fussy eater,just doesn't wanna eat anything, doesn't bite food yet but is only swallowing,,is this normal?

You can consider bringing your child to NUH for feeding therapist to assess your child's condition. Although it's normal that they will still tend to swallow their food but chewing actually helps in their speech development. There are various therapies, methods and tools that can assist you to help promote chewing and biting for your child.

I'll suggest for you to take him to a pd.
