Has anyone else had this problem?
DS is 2. After he's stayed at his dads (especially for more than 1 night in a row), he comes back and his behaviour is much more challenging than usual. More tantrums, more pushing limits - even to the point where he was pushing other children in nursery last week (unlike him).
He's not a perfectly behaved child usually, he does push limits but he's mostly well behaved, he just comes back and is 10x more difficult.
