when other kids ask what is wrong with your child?
My son has apraxia. We were at the playground today and he was playing/having a conversation with a child who was 5. The 5 year old asked me why he talked funny. I didn't know how to answer. I ended up responding that he was just a baby and still learning to talk, to which the child responded that he didn't look like a baby (mind you, my nearly 2.5 year old is about as tall as a 4 year old so not too much smaller than the 5 year old, lol).
I couldn't think of a way to explain apraxia simple enough for a 5 year old to comprehend. I'm sure there's some painfully obvious answer that I'm totally overlooking.
Re: How do you handle..
DS still hardly talks and when he does it's hard to understand him. I just tell kids that he is just like you but he is learning to talk a bit different.
So far it has worked well.
