stepchild

[Mumzyto2]

Hello,
I am after advice regarding a stepchild. My partner has a 9 year old daughter from a previous relationship, we have a 6 and 4 year old together. His daughter moved away when she was 3 and my son was a few months old, she has recently come back and it’s a nightmare, she is nice to my 4 year old daughter but horrible to my son. She excludes him, snaps at him, ignores him when he tries to tell her a story or something, she just sly as well, if he said the sky is blue she would argue with him until he cries. My son is so sensitive, he used to suffer ticks from nervousness, he hasn’t had any for a year until now they have come back. He dreads her coming at the weekends. I just don’t know what to do about it?

What is her father doing about it?

Have you asked her what her problem is?

She is nice to your daughter so the unpleasantness towards your son is deliberate and controlled.

I would not tolerate deliberate unkind behaviour but would want to know why she feels animosity towards him.

their dad will tell her off and i have tried to ask her what her problem is and she just says nothing, and i say you are nice to your sister but not him, why? but I dont get anything back, she will just go in a huff. I have told their dad that i need to protect my son so something needs to change. i know that I will struggle to be able to bond with her either if she is upsetting him. but he just doesnt know what to do as they are both his children.
