My son who is 2 is goin to being going to nursery 2 days a week, he went last we for 2 settling in sessions. One I stayed the other I left him for an hour, this week he went yesterday and today for 3 hours, he hated it this week?! Crying when I left upset the whole time he was there. Really upset not like a tantrum, I feel so bad for him I dunno what to do im starting a new job and I really want him to enjoy going to nursery and be happy to be there, how long will this last when will he like it and realise I'm coming back? How can I help him settle in better!?
