My DS is nearly 15MO. He started nursery at 11MO. It took him a couple of months until he was completely settled. It is now the summer holidays and as I'm a teacher he is home with me for the summer. He has the odd day in nursery during the holidays so he doesn't completely forget what it is like. However, we are going away a couple of times (just visiting family, nothing exotic!) so he won't be there every week.
Will he take ages to settle again in September?
