They'll hate the baby because they both crave his attention. They hate it when I cuddle him! As soon as I'm near him his boy will be like - come and play xbox with me...

Their mum doesn't work many hours at all so my partner feels he has to provide for them. He's upped there pocket money, gives them separate spending money for clothes...
Whatever she isn't giving them he want to give. I've tried explaining that I'm choosing to go back to work full time to provide for my baby. To give him what he needs... not to up his kids money a bit more. He seems to feel this child needs to be treated the same as his others - which I find unfair. Their raised in different families. It's not my fault the mum is to reliant on my partner now and doesn't work to provide for her kids.

I also wanted our first Christmas together as a family. Me my other half and the baby. But it looks like we're spending Christmas eve, Christmas day and boxing day with his kids.

I just feel like me and the baby are going to feel like outsiders in our own home

Thanks so much for the replies already . I know I need to be an adult about it, but I'm finding it so hard having them here 3 times a week, then my partner working 3 late shifts...
I seem to only have him for a day
