Puffin, that's interesting. So far I haven't seen evidence of much theorising, or at least she doesn't try to discuss theories with us, but who knows, she's only just turned 4 wink

Portia, no difference since she's started school. She's just never been a question asker. Occasionally maybe a vocab question, but none of the typical 'why' questions that kids supposedly ask all day. When she gets home from school I'll ask about her day, she'll tell me what she did, then she just wants to kick a ball or run around, play games, dress up, draw, play with her ipad, etc.
