GPs helping out

[ExcuseMeButImHavingACrisis]

SIL has just had twins before Christmas. She already has a 4yo DD.
Do you think it's U for her to call my ILs at a drop of a hat to help her and to for them to go round every time she needs to pick up DD from school.
I have 2 DCs who don't get to see them as often now as they are tied up. My SIL is quite controlling and asked ILs to buy a more reliable car as their current one is quite old so they can come when she needs them.
AIBU in thinking she is being U?

How old are your DCs?

She has baby twins! How hard would that be? Give her a break, FFS.

When my twins were 5 months old I don't think I even knew my own name half the time I was that sleep deprived! Cut her some slack! That support may be all that a getting her through, and you may find as the twins get older she won't monopolise the time so much.
