No doubt this has been gone over before, but any ideas welcome.
DS is very nearly 2. Over the last couple of weeks he has started biting really badly, it's getting worse and worse. It's mainly his sisters (aged 4 & 6) who get it, whenever they do the slightest thing to annoy him, or if he mistakenly thinks they have e.g. yesterday when he thought DD1 had tripped him up - she hadn't, I saw the whole incident, I could see from his expression that he thought she'd done something and went to go and grab him before he lashed out but he had bitten her and drawn blood by the time I scooped him up. Today she has the most awful bruising and teeth marks.
Let me just add (although I know it doesn't sound like it!) that he is an utterly delightful child, generally good tempered, sweet, loving, full of happiness and laughter, great vocab for his age. He undoubtably gets a bit pushed around by his sisters but they adore him and DD1 in particular spends hours looking after him and playing with him and I think that he loves her more than anyone in the world - yet he bit her to bleeding point. He does have tantrums too - usually very violent and with much screaming and lashing out but blown over very quickly.
What to do? My immediate reaction yesterday was to scoop him up, say NO BITING and put him in his cot and walk out. He cried and cried and sobbed, after a couple of mins I went back and picked him up and showed him what he had done to DD1 and he said sorry over and over and kissed her and hugged her etc. Then this morning he bit DD2 v hard over nothing and this evening DD1 got it again. My general reaction is to remove him from the vicinity and lavish attention on the one who has been bitten and withdraw attention from him, but it's clearly not enough to get the message across. How can I stop this?
Thanks
