I know I'll probably get flamed for this but not sure how to handle it. My MIL looks after our youngest whilst I work from home. She also has our eldest in the holidays. We've had this arrangement for 5 years now. There's a few things I let slide as it's grandparents and free childcare but lately we've been having a few issues with screens, a couple of months ago my eldest said 'mummy nanny put a different version on paw patrol on and it scared me' I asked my MIL and she said she'd put it on on YouTube. I said ah okay, probably isn't the licensed real version, can we just do the netflix one from now on. She struggles to work our TV sometimes so cut to today, brushing my little ones teeth and she says nanny put the scary version of paw patrol on again. I know she's meaning no harm, I was on a lot of meetings today and she probably didn't want to disturb me but this is now the 4th time it's happened 🙃 do I just need to be super forceful with her? There's a few other things as well as my eldest grows are tricky to navigate, like teaching her 'na na na na na' and sticking her fingers in your ears like when you're making fun of someone, just odd behaviour and I don't know why she encourages it. I've voiced my concern and option on bits like this but it falls on deaf ears. Any advice much appreciated. This has all been discussed with my husband and he agrees with it too, we don't want to upset her but equally feel we can't let it slide anymore...
