Apologies in advance as I know this will get waffly & long winded but I think all info is relevant.
DFriend has been stuck for childcare on a weekend since before the summer holidays as her mum who provided it previously has had to go back to work herself. DF's main work day is a Sunday as she gets paid double time. I now have DF's daughter (age 10) - I'll call her M - from 8am - 6pm on Sunday and I have my own DD (age 6), DH works away so isn't around unless on longer leave. This all fine, the problem comes with activities etc we do & DF feeling indebted to me.
It was agreed from the start that I didn't want anything for having her, it's a favour to DF & M is no bother at all, both DD & I enjoy having her with us.
DF & I are in very different financial situations, she's a single parent on a low income and her parents who previously helped her out a lot have had their own financial hardship recently hence her DM going back to work herself. DH & I are by no means rich but we're comfortable and have two wages coming in (DH's considerably more but that hasn't always been the case).
On a Sunday M comes with DD & I wherever the 3 of us decide to go. Today it's been the cinema, last week trampoline park, we've done a theme park one week, swimming etc. I honestly do not begrudge paying for M at all, whatever DD gets M gets the same (popcorn at the cinema & so on) it's not a problem but DF is getting anxious & said she feels that she's taking advantage of me and said it feels like charity.
She's attempted to give me £10/£20 when dropping her off which I've said I don't want, she's insisted a few times, I kept it to one side then gave her it back when she was going food shopping as I knew she was short after getting school uniform.
Now she's keeping a list & is insistent that she will keep a record & pay me back which I know she can't afford to do & I just honestly do not want it but she just doesn't see it that way. She said it all adds up which yes I know it will but it's not enough to effect anything for us, I've tried saying it's only what I would spend if DH was time with us on a weekend anyway. I've said just to get me a nice candle or something at Christmas if she really feels she needs to get me something in return.
I'm starting to feel wary of doing activities & things with them as I don't want her recording it all on her list but the truth is I would rather take them out & do something to break the day up. Also now DD is back at school during the week she wants to do things on a weekend. Plus I think it's going to get harder now the weathers turning as we did a lot free things on the Sunday in the summer such as beach, splash park etc.
This isn't every single Sunday, sometimes we'll just do swimming for a couple of hours & be at home the rest of the day do some baking, DD & M playing computer games, watching TV etc.
We've been friends since our first day of primary school 30 odd years ago, she knows me well enough to know that if I say I don't mind then I don't but it's just getting awkward & I don't know how to get around it.
