I am 20 years on from you op.
You are right to say something, I did, but nothing really changed after a brief effort. They just fell back into the same pattern. I too didn’t want childcare, I wanted a relationship both with them and the children. I had to really revise down my expectations, because it wasn’t particularly forthcoming.
Looking back I had hoped so much for a super close family, but on reflection they were not massively involved parents so why would they be the second time around?
I stopped the hosting - it was too tiring and we would just meet for a day out, a picnic and the relationship did become more distant, which in the end was fine because I made my peace with it. They were happy and we found a very trusted older lady to take care of our dc when we needed childcare and just stopped asking them.
They didn’t even help without a massive fuss when my dc was unable to breathe and blue lighted to the hospital, that’s when I realised what I was dealing with.
I had therapy and realised my dc didn’t need grandparents to be happy, they just needed relaxed and supported parents. So we made a fantastic network of friends and got on and enjoyed our lives.
My dc are older now - almost fully grown and have zero interest, which is a shame but you reap what you sow in life.
