Why has she started biting so viciously suddenly?
This might sound a bit off the wall and I may be totally wrong – but reading your post it seems to me she bites when something nice is happening – e.g. when you were ticking her and when you were having a cuddle. The biting may not be malicious – 3 is still young for them to sometimes to deal with their emotions – it may be her emotions are bubbling over inside her and this is how she copes with the feeling sounds daft now I have typed it but going to stick with it anyway :0) – I have no advice as my son never bit but because he was autistic I was given tips from his behaviour nurse to deal with it if he did When she bites you rather than push her away which will injure you more push her face gently but firmly into you – this makes them open their mouth because you have blocked their breathing – also prevents you tearing your flesh if she has her teeth tight on you when you try to pull away or push her off.
Her age would help to answer this question, however almost all children go through a “biting” phase. She goes to a nursery, and even though they may have not seen it happen another child has probably bitten her that is usually what causes it. Unfortunately with you not spanking your children, and doing nothing about it she will continue to do this!! You are going to have to do something to let her know that you will not tolerate this kind of behavior, ie…maybe you can find a book at the library about not biting or put something in her mouth that she does not like the taste of every time she bites, and when she goes to bite she will remember that you will put that something nasty in her mouth.
Is it possible she could be jealous of the baby? It seems like when you play with her she’s biting you so you’ll give her full attention, i know sometimes older siblings reject the little ones, Maybe you guys should teach her about how hurting others isnt okay (She needs to know not to bite by the time she reaches kindergarten, now would be a good time to teach her) Instead of taking away sweets and teddies, i reccomend telling her “NO, we do not bite” (You have to be stern and clear) taking her out of the situation (Right when she bites, put her in time out) Get her a little mat to sit on in a corner of a room, and leave her for ten minutes alone. Come back, and tell her why what she did was wrong. Tell her Its not okay to do, and make her apologize to whomever she did it to, and give them a hug. Aside from disciplining like that, You guys could start some positive activities where she feels as if she gets attention (Maybe have dad watch little one and take her swimming for an hour or
