Does my son needs speech therapy

Noemi (no eh me)

I think my son needs me to work on c d g t l n m sounds

Before it was Nook= milk now nilk

Tar= car

datty daddy

Tat =cat

My husbands cousin metioned he might need it cause confuses how the letters are pronounced

Sometimes its hard to understand him but i love that he finds wordsor sounds to discribe what hes trying to say, so i can understand him.
