My ex partner hit our 3 year old and badly bruised him 6 years ago, I reported it and he was convicted of assault.
Over the past 5 years access has resumed but I have always been afraid to completely trust him alone with them so regularly spent time with them all. There have been a couple of occasions where they have complained about being smacked of ill handled and the Child Protection Services have become involved, but for the past 2 years there have been no incidents.
3 months ago my ex became involved with another woman (a mother of 3) He'd promised to keep his new relationship separate from our children for the first 3 months as I felt that they needed a transitional period, and he needed to see whether it might go anywhere, but he introduced them all after a week.
My supervisory role has had to end, obviously to make way for this relationship. Now virtually every time they see him, she's with him.
Over Christmas he had them all stay over at his for the 2 days that he had ours, mine say it was boring and noisy, Dad kept shouting at them and his Girlfriend kept shouting at her children.
When she went home with her children, he had a day left with ours alone. My 9 year old has since said that his Dad has smacked him on that last day.
I immediately revoked his access but have not reported it as the smack was not sever.
I do however feel that I need to warn this woman (who I have not met) of his past and what happened after she went back home. (He said she's already aware of his previous conviction) I've written her a brief letter, but I'm putting off posting it. I'd really like to know what anyone would do
