Problems with step son and father

[birty]

I have been with my partner for six years and have have his son every weekend Frid to Sun pm since he was two and half. My step son has always had behaviour problems and the problem I'm now having is the back chat and recently he raised his hand to me. My partner does not give me his 100% support and back me up when he's behaving in this way. My step son is eight and I have two boy's of my own and I'm frightened that they will start to copy! I have spoken to my partner many times regarding support and that I feel like the wicked step mother. Need advise help!

Hi birty . I'm a stepmum to 2 boys aged 10.5 & 12, we have them 50%.

Although I've been fortunate enough never to have had the boys say anything or behave in a way that would not in front of their birth parents, I really do think that having the back up of your DP is 100% essential. Discipline can be quite a hard thing where step-parenting is concerned, I think we tread a fine line. I had to sit down with DH (then DP) and discuss my feelings with him, it turned out he genuinely did not see that my issues were problems. The discussion really helped sort things out.

Have you told your DP that you are worried that his DS's behaviour will start to rub off onto your DSs?
