...and hoping you lovely ladies can help...
My DN is 20 months old. He's also profoudly deaf but I am starting to get a little concerned that there is more to it than "just" the hearing. But obviously it's hard to tell what is taking longer to develop because of the hearing and what might be something else.
He doesn't have any vocabulary or meaningful sounds (e.g. animal sounds)
He never responds to being told No, or Dangerous etc, but he does hear you (with his aids) because if you offer him food he comes running!
He repetitively does things like opening cupboards and you literally cannot leave him unattended in a room for a second as he will destroy it, unlike the other 2 toddlers in the family.
He puts EVERYTHING in his mouth. He crunches gravel/sand/mud. He also licks things - completely random objects.
His twin (hearing) has learnt the Makaton sign language being used in the home for him, but he doesn't sign.
He's very small and doesn't seem as physically adept as the other toddlers of the same age I know but he's extremely good at puzzles but isn't interested in anything for long (ok that's normal toddler behaviour).
My parents keep asking me if they think he's normal and I don't know what to answer because if I'm completely honest it doesn't seem 100% normal to me. But then I only have my son and his peers to compare him too and the hearing problems were always going to mean he takes longer to pick up speech.
What do you think? Do you think there might be more to it than just the hearing?
