Am I the only one who hates this

So I have 2 kids (Girl aged 2 and boy 4 months) they both have different dads, my partner now treats my daughter as his own and has helped bring her up since he met her. She sees her "real dad" one day a week for a few hours which he's happy with. So with my little boy now, my partner has a big family and a lot of them still haven't seen him, I dealt with a lot of postnatal depression and anxiety and still get my bad days. A lot of his family don't talk to me etc or have asked to come and see him. A few have said to my partner "when are you gonna bring the child down to see us we haven't seen him etc" but why should it be up to me and my partner? If they want to see him they ask to come to our house?
