Ds has been in a lovely nursery 3 days a week for last few months. He is very settled and loves it. But, over the last few weeks he has been bitten several times. I have tried to be understanding and not come over all PFB. The staff have a plan in place for the biter etc and.I'm v aware that on the other side of this is a very upset mum of another toddler and I know I'd be distraught if it was my ds who suddenly started biting. I've spoken to head of nursery who has explained what's being done but I wonder if I should be doing more? Of course I don't want ds to keep being hurt and I feel very guilty about him being there and not protecting him etc but also don't want to massively over react. Should I be doing more? Ds is very robust and does not seem to be upset by it (over and above the initial shock/pain of the bite if that makes sense) and according to staff is fine after a cuddle. He has been bitten once since the plan was put in place. I want to have another word but DH says they are doing what they can and we should leave it for now. WWYD?
