DS is 3. Over the last few weeks he seems to have forgotten how to speak properly and most communication is a horrible squeaky whingy noise accompanied by lots of foot stamping, arm flinging and pointing. He is having a moment now, making the screeching noise and banging his feet. The reason? A piece from his Charlie & Lola game has rolled under the sofa and instead of asking me to get it for him (like he normally would) he has decided to turn into some kind of monster!!!! He doesn't tell us when he needs the loo, will just stand there screeching so usually ends up with wet pants. He won't ask for things, like if he wants a drink or wants a certain toy/book/whatever, he just does that horrible sound and expects us to know what he is on about. It's like he is a baby again. What's going on???
