Is this really common, or a sign my child's not happy? Ds is 3.7, has been at same nursery since 1,does two days a week of 7-8 hours, and when he gets back home is just so bad tempered and cross - often endless rows til bedtime. I know it's a hard transition, but I can't think how to make it easier for him. He's about to start a third day (not consecutively) and I'm wondering whether this will help with adjustments (the other days he is at home with one of us) - or not. Any thoughts? Thanks!
