DD1 (nearly 3) is expecting a sibling in 6 weeks or so.
She has started being uncharacteristically clingy at night and last night she came into our bed - which she has simply refused to do since she was 8 months old (!) and started cuddling me and her father (she is NOT a cuddly child).
She hasn't given any explanation for her behaviour and said she doesn't really know why she didn't want to sleep in her bed last night, although she said she will tonight. (Hmm!)
Is it common for toddler's behaviour to change before the birth of a sibling? Is this anxiety about change, or a worry about leaving me 'alone' in case the baby arrives? In general she seems quite excited about the new arrival (although obviously her understanding is limited).
