Biting at Daycare

[user1478514376]

I am just looking for a second opinion. My son is 18 months and started nursery 5 weeks ago, going for one day a week. He still cries when I leave and is sometimes crying when I collect him. The staff say he has a lovely day but I do worry that he’s upset while im not there. This worries me but I know it will hopefully get better with time. What does bother me is that a couple of weeks ago he was bitten quite badly by another child, when I questioned this I was told there is a child with behavioural problems who they are monitoring closely. I was really upset as the bite was in the middle of his forehead and took a while to go away. On Friday when I picked him up he has scratches all down his face where apparently a child had tried to snatch a toy from him. Is this normal behaviour in a nursery or is this something I should be worrying about. I am a first time mum and quite concerned. I feel like taking him out altogether but maybe I am over reacting?
