My daughter is almost 4.5, and more recently she has been biting her sibling (2.5 year old brother). It is always in anger and response to him not listening or irritating her - but it happens very quickly and I haven’t always been able to intervene before it happens.

She is a smart 4 year old, and can communicate well. She articulates her feelings and needs/wants really well most of the time, but in some moments she gets so angry and bites.

My immediate response is to seperate them and tell her that biting was the wrong choice. I move her to a quiet spot whilst I help her brother, and then she wants to talk about it. We have good discussions and have spoken about how it hurts, she wouldn’t like it if someone bit her/ hurting people is the wrong thing to do etc.

She gets really upset about it and always checks on him afterwards.

But it’s not getting better, feels like a weekly occurrence.

Advice for parenting approaches? Time outs? Taking things away? See a Paediatrician? Always keep them apart from playing together?

I’m really at a lost and failing both children.
