Have two young kids and in laws (MIL, stepFIL and SILS) often ask to have the baby, sometimes both kids - don't mind, gives me a break, but I never ask them, they always offer and I am so grateful when they do, even though there's always more than one adult at home I feel bad for asking them for help so I don't often approach them for childcare myself. MIL remarried and has two School age kids herself and sometimes when her adult kids from previous marriage can't look after them or when the adult kids want to go out themselves they'll ask me. DP is at work so that means I'm at home with all the kids.
I don't know if I'm being unreasonable because recently I just don't want to take them in the school holidays? It's so hot, I'm struggling myself with the heat and the two kids and trying to get everything done in the house, I'm on my own apart from evenings and weekends. But I just feel like because they offer to take my kids all the time without me mentioning or asking or giving any hint of "can you take them" I feel obliged to reciprocate but I just don't want to and I feel like such an arsehole for saying no and I'm afraid they'll mention that they take our kids all the time so I should give something back.
(As a comparison I can always ask my parents for help with the kids and there is no feeling of obligation nor would they make me feel obliged to do something in return just because they helped out with childcare.)
So is it really shit of me for feeling this way?!
