Grandparents make no effort

I’m not expecting any handouts or babysitting gigs from my parents for my 3 under 4YO kids. All I Ever wanted was for them to have a relationship. That is non-existent, my parents feel that I should be responsible to bring the kids to them. Which in turn they don’t have to come over to us. (15 min. Drive) My mom is a SAH and my dad works still. I told them last time they need to come over more because at their house the kids have no corner to play. Everything is untouchable and it’s exhausting to visit. My mother got defensive and snappy and said, “then don’t come!” Instead of being mature and understanding and work with me on it. I really think if I don’t contact they wouldn’t bother initiating. They make no effort to call or ask anything. But I still get complaints how “far” we are and how much they love them but don’t get to see them so often. No one is stopping them except themselves. Inviting them for anything, Xmas, birthdays, BBQ, is like pulling teeth. I have to convince them first. I’m seriously getting fed up and have resentment, They say they love my kids but act like they don’t give a shit about them. I bluntly told

My parents that one time and they act dismissive with a bunch of excuses. Should it all fall on me? Am I responsible that my kids go to see their grandparents? Shouldn’t the adults make the effort to see kids?
