DS (2.4) talks quite well for his age and is very imaginative, I'm starting to wonder his fantasy life is going beyond 'normal' though. For example he will often tell me (very earnestly) things like he's 'been on a helicopter to see grandad' and recently he told me that he'd broken a window at nursery (I'm sure he hadn't). Today he'd 'seen a cross man at Daddy's house' (XP said no one else was there). He can be very insistent that these things are true - is this normal??
