Reading through this thread, I can see this situation is the antithesis of another thread, "new here wanting advice" where many paternal grandmothers felt at times they were down the pecking order somewhat in the time allotted with the grandchildren. Here I see the other side. Personally I don't want the all encompassing role the maternal grandmother of our gd has, insomuch as she appears to be very one dimensional her raison d'etre is being mother and now grandmother, she will drop everything and have gd for a week at a time during school holidays if son's partner needs a bit of "me time" although she doesn't take the new six month old baby as well. As far as I'm concerned she indulges her daughter's whims when she should be telling her to deal with the choices she has made insomuch as she knowingly and willingly opted to become a mother at 19. She was too young, but her own mother did not try to dissuade her daughter in any way, inspite of the fact that she would have known that she is an immature person who finds the day to day rigours of parenthood dull. Predictably a few years down the line feels that she is missing out, but not enough not to have another shot at it. Although the new baby's a boy, with a slightly different character, it still seems to surprise her that once again at six months old he is wholly dependent, thus stopping her having her "me time". She actually told my son his "me time" is when he goes to work! A while back she was bemoaning the fact that one of her friends had to beg her mother to babysit her child and would only do it very occasionally and made the comment "that the friend's mother was a bitch, it was a grandparent's job to look after their grandchild/children" to which my husband responded with "no it isn't our job at all, it wasn't our choice to become grandparents, it's a role people have thrust upon them, that's not to say we don't enjoy it, but our role is occasional and one step back". Although we are happy to have our grandchildren, we do make it clear that we have our own lives and other interests and we have been criticised by both son and girlfriend for doing our own thing too often, having too long a holiday at times and generally not dropping everything as and when requested.
mumcooper, I empathise with your situation, you sound very put upon I think some young people expect far too much in babysitting duties from the grandparents. I'm sure some of these new parents' perceived sense of entitlement for stretches of time without their offspring are fairly new, I can't imagine previous generations putting up with it.
