DS is 17mo and has been going to nursery since the start of July. He's been really settled after the first couple of weeks and even took a move of room at the start of Sept in his stride.
However for the last week, he's been really upset at drop off - no idea why as there are no changes at home or at nursery (same lovely key worker).
He's fine walking to nursery, it's just when he has to leave me/DH that he gets upset.
Any ideas of how I can help him? It's horrible to leave him so upset (although I know he's fine when he's there)!
