My 18mnth old is at nursery full time. We love the nursery- they are warm and kind and she seems to enjoy going. But they literally ring every other week at some point in the afternoon to inform us that she has banged her head. I don't mind the calls (it is obviously their policy)... but I do mind how regular the bumps are. They are not serious- but she literally never bumps her head at home and we are pretty relaxed/not helicopter parents (we let her free in the garden a lot). I just have my eye on her I suppose. She is naturally a cautious and stable toddler too- not a boisterous one or a bit unsteady on her feet.
Is this normal? What should I say to the nursery??
