Talk to your Health Visitor team with your concerns. It's important if he requires early intervention they are aware. What did they say at his 2/2.5 development check? Best of luck x
We have had one session of speech therapy, my son struggles with speech but not understanding. The tips they have given us so far have made things better. They do all progress at different ages.
