Hi, I hope it's ok to post here. My son is quite young still (21 months) but he has no words at all. People keep telling me he's lazy or a boy or he is just taking his time etc and I really really don't think that's the case.
His understanding is fine, his engagement is fine, he just cannot form words. I can see him trying and recently he has started to look embarassed and annoyed if we try to get him to repeat sounds.
I never say 'say this' because that annoys him but even if I point at an owl for example and say 'twit twoo" really clearly and look at him, he can't say it and he puts his head behind his hand in a dismissive way.
So I want to approach things in a way that won't effect his confidence. At the moment I strongly believe that he cannot form words, everything is just 'ahh' or 'urgh'
So I want to help him communicate with sign language and picture cards. I'm learning makaton, but I just wanted some advice from anyone who has been in the same boat .
Firstly, has anyone had a child like this whose understanding was fine, physical development fine, engagement fine but just cannot make sounds, and if so did they 'catch up' or was it a speech disorder?
Also, how do you go about using picture cards with a child this young? Any techniques or ways to start? I'm wary of putting a picture of all his fave foods in the kitchen for example in case he always points to biscuits and is constantly reminded of biscuits 
I feel like he's too young for pictures of facial expressions/moods?! Should I buy a set of.flash cards from amazon and do you have any recommendations of good ones? Do you put the cards in a book and get the book out when they are frustrated or stick them on the wall, or what?
Any advice would be so greatly appreciated. Thank you.
