I have a SIL who has two kids. We have had issues in the past when she’s knowingly brought them to family Sunday dinners/ soft play etc.with them having sickness bugs- she only mentions it as they are leaving and as you can imagine it spreads through everyone there like wildfire.
She has just had covid and went to her mums for dinner two days after testing positive and her mum welcomed her in. Obviously this had a knock on effect. Her mum (my MIL has a huge inability to say no to her daughter)
I have premature twins who are 10 weeks old. Yesterday my eldest was a bit under the weather so we stayed away from the big family Sunday dinner that my MIL summons us to once a month, only to find out SIL and partner were there with kids loaded with cold and hadn’t told us about it. Thankfully we had stayed away. AIBU to expect SIL, and MIL to at least let us know when they’re ill? I would have been furious if I’d got there and the kids were snorting and coughing over my tiny twins, who have had lots of problems with feeding, weight gain, and hospital re admissions since birth.
SIL is an incredibly selfish and self Centered girl. Her mum does everything for her as she’s completely incapable, and is absolutely terrified of upsetting her precious only daughter.
I know the twins will catch things but at this stage in the babies life I’d rather try and avoid viruses if I can. My eldest had serious bronchiolitis as a baby and she had a lot more reserve than these twins do.
