My baby DS is 6mo. My cousin came round to visit with her 4yo DD.
Baby has some toys, obviously nothing really for a 4yo to play with but I didn't mind at all her playing with the baby toys.
4yo started getting a little bit naughty (probably bored) & was snatching toys off the baby. Cousin, her mum, didn't say anything to her about it. Eventually I gently told her not to snatch, he's only a baby etc. Cousin not phased, didn't say a word to her. She didn't stop doing it so I started wrapping up the play date, picked up baby & said he was due a bottle, that sort of thing, to signal it was time they went home.
4yo started making a fuss when cousin said it was time to go & she was flustered. 4yo had baby's rattle in her hand & looked like she wasn't going to put it back. I nicely asked are you going to put the rattle back? They both ignored me. Cousin started saying bye, thanks for having us, 4yo still had hold of rattle. I said (nicely again) I'll take that rattle off you now, & she started kicking off really bad, screaming, crying etc. Cousin said nothing to me, just looked at her DD & looked blankly at me. I tried to tell 4yo it was baby's & baby needs it so it has to stay here - more screaming & crying, still no input from cousin. Then cousin says to 4yo, maybe SureJan will let you borrow it until we come again? I said sorry, no. Cousin rolled her eyes at me & said 'really?' in a very pissed off tone, & I stuck to my guns & said yes really, it's not hers to take!
Cousin cajoled & begged 4yo for a good minute or 2 to hand it over, with her screaming full pelt in her face, & eventually cousin snatched it off her, threw it onto the floor & dragged her out of the house saying 'thanks for fucking nothing' to me!
WIBU? Part of me feels bad because it was just a rattle & baby probably wouldn't have missed it, maybe I was being a bit mean? I'm sure cousin thinks I was just being awkward & making her suffer through an embarrassing tantrum that I could have easily stopped by letting her take the bloody thing.
But part of me thinks no, it's not my fault she won't discipline her DD & why should I just give her stuff to take home so that she gets an easier time? It was a rattle & she's 4yo so not age appropriate for her, I feel she was just pushing boundaries & didn't really want it.
I know it isn't my place to tell cousin how to discipline but I do feel she should have stepped in way before the rattle incident by telling her DD to stop snatching, play nicely, be gentle with baby etc. It annoyed me that she didn't!
Am I mean/unreasonable? I have no doubt that there will come a time when baby is older & tantrumming in similar fashion & I'll be able to empathise more, but I don't think in that situation I'd let him take the toy to keep him quiet.
