The title says it all really, DH and I are fairly speechless tbh. I'll just be sat there, and he'll crawl up sneakily, smile an angelic smile and sink his teeth into my big toe. He's not fussy either. He's done it to family, friends, his key worker at nursery, even a lady who came to visit the nursery with crocs on.
I do usually give him a firm 'no, that's naughty to bite you'll hurt mummy' or similar, but he just gives me a withering look and crawls off.
What am I meant to do?
