speech and potty

So we took our little one to his 2 year old check up and they said he should get evaluated for a speech delay.  Apparently by 2, you should have 50 words in your vocabulary and start combining 2 words together, like "mommy up" or "daddy go".  Our NP had said they should speak 20-30 words by now but the evaluator mention only 20-30 words at this age would be a concern.  Our son doesn't speak any words really.  He tends to drag us and point to what he wants.   He has lately been saying mama and dada more but he still doesn't say it to call me and get my attention.  He just says it when he sees me.  He says random words every now and then and does babble in his own lingo.  Anyway, after the evaluation by the specialist and a speech pathologist, they felt he wouldn't qualify for early intervention because he is only delayed in one area which is actual speech.  Usually to qualify they need to be delayed in at least 2 areas so typically the child would have a delay in speech and and in speech cognition but our son seemed to be fine in everything else they examined.  We didn't get the final report yet, but that's where we stand as of now.  I'm thinking he's just a late speaker.  He is able to communicate his needs even if he isn't actually talking.  We'll just need to keep encouraging him to repeat sounds and words even if he doesn't reply necessarily.

My next big challenge will be potty training.  I have no clue where to begin.  I was waiting for him to be able to talk so he can let us know when he has to go, but with his delay in speech, I'm thinking we shouldn't wait for that.  I saw this great product on line that I think will be useful. For boys, it might be a little messy to use but a porto-potty for toddlers sounds perfect to have when traveling outside the house and you can use at home as well.  I haven't purchased it yet but it's on my wishlist.

I already purchased a cushioned potty seat for our house toilet.  I have yet to have him try and use it.  I think I may introduce him to the potty by showing it to him and letting him sit on it and see how it goes.  I've already spoken to him about being a big boy and using the big boy toilet so at least it's in his head.  I'm not sure if he comprehends what I'm saying but he is pretty good in that respect.
