My 4.5 year old is in reception. She is quite shy and quiet in class but at home she is the opposite. Over the last few months I have started to find her behaviour so challenging, particularly after school but at all times really. She is loving, but can also push and kick her younger sibling, and this morning she bit them. Sometimes she shouts, and she isnt great at listening. I have tried talking to her, praising her for positive behaviour, time out etc. I feel out of my depth though and am worried I am handling it wrongly and making it worse or that there is an underlying issue so would really appreciate any advice anyone has. I know she's suddenly got lots of boundaries at school so is almost having a release outside of school but this seems extreme. I plan to try a sticker chart this evening although in the past incentives haven't made much difference. Thank you.
