Welcome lotus - and congratulations on the little one.
I'm another who thinks you will probably see the new little family about as much as you have been doing.
I have 5 children, three with children of their own. Mostly I see them about the same as I did before the babies came along - though I do go to cricket matches and swimming galas etc now the children are older.
I think we are a close family - though most definitely not in each others pockets - and I'm happy to drop everything in an emergency.
I don't do any regular "daycare" for any of them though have done so for periods if needed.
Like Grammaretto I lived a long way from parents and in-laws when my family was growing and, like her, I was not prepared to hand my babies round so everyone got a "turn".
I think we all find the way to be the best parents we can be. The solutions are different as we are different people.
Be patient. My own children loved my parents dearly in spite of the distance and irregular contact. Please try not to worry.
