I'm almost 100% positive I'm not BU but just in case.
I was visiting MIL today and SIL was there. For context, we both have two children, and SIL's youngest is a few months older than our baby who is almost a year.
So MIL asked me how DC2 was sleeping. My children have been notoriously crap sleepers, we cosleep as a result. I don't think MIL approves of our methods but hey. I said that we had been getting the baby to sleep in the cot and it finally seems to be working. We bought a My Hummy a few weeks ago and it's worked so, so well. Baby seems to really respond to white noise, sleep still isn't perfect, but it's miles better, thank you My Hummy. Baby loves the MH too, smiles at it, squeals at it, gives it kisses. Best £50 ever (and that's a measure of how tired we were!)
Anyway SIL goes, oooh that sounds fab, I wonder if that would work for my DC. I wasn't aware that her baby was a bad sleeper as to be honest she's always been very ready with her advice - she had hers in the cot a lot sooner. I just said well, it might do, I thought it was a bit late for it to make a difference to my DC but it has helped.
SIL says, great, I'll borrow it for a few nights then.
I thought she was joking at first, so I just laughed. Sil looked quite huffy, and I started to realise she was serious. In an attempt to lighten the mood, I said "you'd have to prise it off the cot first, anything that gets baby to sleep is going to be superglued on"
SIL just sort of pursed her lips and said "well I'm sure we can borrow it for a few nights and DC won't miss it"
At this point I saw my baby free evenings slip away, and I maybe was unreasonable - I replied "no, sorry, by the time baby stops needing it you'll hardly need it for DN"
MIL at this point wittered something about how lovely it was to have cousins who could share. I left soon after, there was an atmosphere I felt.
About an hour after I got home, SIL (Queen of vaguebooking) posted a generic meme status on FB about how family might not mean much to some people, but it means everything to her and she'd do anything for hers. I kind of assume this is a dig at me refusing to relinquish My Hummy.
DP thinks I should just lend it to SIL as otherwise she'll cause a fuss and make it into a whole big deal. I told him he was welcome to lend it, if he was prepared to do every single night waking in its absence. He soon piped down.
SIL was BU to ask, wasn't she? When she knows how difficult sleep has been for us?
