Ah, Uptherear, I feel your pain! We have the same situation here, except it's both sets of GPs doing all they can for the other grandchildren.
We live about 2 hours away from our parents, and both have siblings who live within 40 mins of them.
The stuff our parents do for our siblings and their kids would blow your mind! MIL gets on the bus at the crack of dawn every Weds so she can go and get the grandchildren to school, she hangs about SIL and BIL's house all day and then collects the grandkids, then gets bus home. MIL first had my nephew to stay overnight when he was 4 weeks old (SIL needed a break).
When my DS was 4 weeks old, my DH went into hospital for an operation. He was then on bedrest for a number of weeks. No one came to help us, except the night before - in laws came up to drive DH to hospital. They left the day he came out.
My parents do loads for my sister - absolutely tons. They must have the kids over once a week, plus they go there and stay for a week in the summer so my sister and BIL can go away.
When my DH had his 2nd op (in hospital for one week then bedrest for 8 weeks - DS was 18 months old) my parents came over for one night "to help".
They took me to the hospital to visit DH, that was it.
When it came to DH's 3rd op, I said that we were ok for 'help' but maybe they'd like to come over and take me and DS out somewhere, as DH was on bedrest again and we wouldn't really be getting out much. To give them their due, they did come for 2 nights. Did nothing to help, but we had a nice time.
I've lowered my expectations now. I don't expect anyone to help us out, ever! If DH being in hospital so many times over the last 3 years, plus DS being ill (call-the-ambulance style of ill
too many times to count) hasn't brought out the desire to help, then I don't think anything will.
We just get on with it now. I'm very lucky, I have some wonderful friends who give me all the support I need.
Expect nothing, and when you get nothing it's not so hard to accept,
