My MIL is lovely, so compared to some of the MIL posts we see around here this is such a minor, silly problem!
Nevertheless, I'm not sure how to approach it tactfully, or if I should just suck it up and deal with it (which I probably should, but maybe someone has some good suggestions!).
So MIL will take DS for the day about once a month and they have a lovely time and I get an extra day's worth of work done. Great! But he comes home smelling very strongly of her perfume and it smells terrible to me! Not just hers, I don't like any perfumes or flowers or fragranced soap or anything like that. But he usually comes home so worn out from the exciting day at Grandma's that I don't have time to give him a thorough scrubbing and wash his hair before he's ready for bed (because I really don't like trying to wash the hair of a tired, grumpy toddler!). And we co-sleep so I'm kind of stuck with the smell all night. And I have to wash all of the clothes and things he's taken even if they're otherwise still clean because they all come back too fragrant for me.
I haven't said anything because I don't want to offend her and I am really grateful for her help and for generally being a cool MIL.
But, is there any polite way I can ask her to tone down the perfume on days she has him?
