Hi my DS is 3.5 and has been at the same nursery since he was a baby. In his current room - the preschool one - his behaviour has become more challenging. His worker has informed us he pushes other children and sometimes pulls their hair. He can shout if they have a toy he wants or if he doesn't like what they do. We are keen to support him (and of course in turn the nursery) the best we can. What is developmentally appropriate here in terms of how we can support from home? He has a good set of friends at nursery but definitely doesn't like going this year compared to previous years and goes through phases of being upset at handover. He says everyday he doesn't like it.
