Irritated with my family

So I just had my first baby in May 2019 and I mentioned that my parents and anyone else that planned on being around him frequently should make sure they're caught up on their vaccines. Mostly Tdap and flu shot. Of course they didn't 🙄 and as long as they aren't sick and are washing their hands I don't make it into a big deal. Well my sister is about to have her twins this week and said to all of us "I know Britt is probably caught up on her shots, but you guys should get them done too if you're behind on them." So of course they're making sure they're caught up on their shots now. Like what the hell?? Were my wishes not good enough? Is my child's health not as important to them? 🤬 I feel like there's always a double standard for me/her and my kids/her kids. It's really starting to get on my nerves now that I have a child and another on the way. When it was just me, I didn't let it bother me as much because I was used to it.... At least they'll be up to date on their shots when this one is born 🙄
