My 10 month old is delighted to have four teeth, and is into biting us at the moment – face, hands etc. It really hurts sometimes but she finds it funny. I may be to blame for this as I’ve always chomped on her cheeks and belly to make her laugh so she could be copying me. From other peoples’ experience is this a phase they go through when they’re teething/exploring sensations, or do I need to teach her that it’s wrong? I do say “no” when she does it, is there anything else I can do? I don't want her to start taking chunks out of other kids at nursery.
