My husband has DC with his ex and we have 1 together. She also has another child with another ex (SS is 9, this other child is 5 and our son together is 2).
My husband and his ex are both working on Monday (the BH) but I'm not so I've agreed to help and look after SS on that day (would usually be mum's day but not bothered).
Last night she messaged DH asking if I'd be able to look after her other child too (the child that's not even my step child!).
This child is 5, I don't really know them that well only met a handful of times, they've never been to our house for any significant amount of time and certainly never looked after them before.
I know she's struggling trying to find someone but AIBU to say no? I have my own DC and my step child to look after on Monday never mind adding a random kid in I barely know?!
For info, I believe her dad is next to useless and not really involved.
