I am a little worried that my ds who will be 4 in October has a really bad short term memory. When asked what he did at nursery, what he ate for lunch, who he played with and most importantly, yesterday, after a day at a castle, about which he was really excited and had a great time, can't remember anything. I don't think he's being obstinate, he could be being lazy but I'd like to know if I should be worried. what's anyone else's experience of boys' memories at this age?
