My dd is nearly 13mo, she has been biting for nearly 5 months, mainly when i'm trying to get her to sleep i.e. cuddling and lying next to her (we co-sleep) She finds it really funny and if we react by pushing her away etc, she loves it, same with being firm, telling her off. Obviously she's after a reaction, and it's hard not to react as it hurts! We've tried ignoring and lifting her away calmly, she just does it again and again laughing. We cant leave her as she follows. It's quite upsetting and means we're still having to get her to sleep every night in the sling round the block. I want to teach her to self settle but it's impossible with her biting! Does anyone have any advice?
