OK, so I know I might get hauled over the coals for this... but I'm honestly in a muddle!
My MIL is really not very well off. She works in a charity shop one day a week, and looks after her very elderly and ailing parents the rest of the time. For one day a week she comes to look after DS. She loves it. It helps us out tremendously. We pay for her to get here plus a few extra quid, about a fiver I think, so she can go for coffee or lunch somewhere with him. I know it's not much but we can't afford much.
My mother, on the other hand, is in a completely different situation. She doesn't work, and hasn't had to work for about 15 years. She is officially a lady of leisure. She drives a Porsche, lives in a house worth over £1million, and is about to move into a house worth over £1.5million. She is always moaning about not having any money which really gets my goat. DH and I do struggle financially, as I'm working part time, and he is a freelancer, so our income is very unpredictable (while the outgoings are horribly predictable!!).
Despite MIL looking after DS one day a week since January, my mother has so far refused to look after him regularly. she said this is because she 'wouldn't want to commit to anything regular in case I want to go on holiday or something'... basically, she just doesn't want to do it. Fine. I've come to terms with that (which might sound dramatic, but my mother has a long history of making me feel like she can't be arsed with me, so these things can grate!). From September I'm going to be working alternate Thursdays, and my mother has agreed (with pressure from my sisters, I think) to do a trial with looking after DS every other Thursday. This is a huge improvement from her initial reactions to discussing her involvement in childcare, which used to be a very snappy 'you must be joking!'... So, it's a positive step, and will be of enormous help to us. In some respects I think 'too little too late' but then the positive side says 'better late than never' (I don't always think in clichés, by the way).
Now, me being all into equality and fairness, I feel I should offer her the same amount of money as we're giving to MIL. Problem is, my mother really doesn't need it. But I know if I offer it, she will take it. I'm stuck between wanting to be fair, and feeling like 'actually it's about bloody time you did something to help, and I don't want to pay you for it!' which I know is really tight-arsed of me, and really it has nothing to do with the money, but more to do with the balance of power in our relationship.
Given all of that, AIBU to withhold the pittance we would be giving her?
I await attack....!
