So toddler is 2 years 3 months and barely says any words. If I count up he can probably say 20ish words but they aren't clear and he only says them when he wants to (meow, oink, blue, nanight)
His understanding is fantastic, he recognises colours, numbers 1-10 and all shapes and is just generally really quite bright. But he won't talk. If I ask him to repeat a word...he won't and I'm freaking out. My brother keeps mentioning autism?
He's a really well behaved toddler, only having tantrums when we put pants on and his new coat 
He smacks the floor if he is getting frustrated also.
I read all the time with him and constantly talk and describe things.
Am I being paranoid or should he be saying more?
