we didn't have much of a problem with biting but i followed what my MCHN recommended - as painful as it is, don't squeal (hard, i know!) because they do think it's a game. take them off & say no firmly. my MCHN also suggested that if doing that isn't enough, place them down on the floor safely & don't allow them back on. i've only ever had to do it once or twice & it definitely worked because DS realised that he wasn't going to get what he wanted! i also tell DS that it hurts mummy to do that. no idea if that sinks in but i figure he understands a lot more than i realise!

hope she stops soon
