Do I have the right to be pissed?

Get ready it’s gonna be a long one...

So my uncle died unexpectedly a couple weeks ago (not covid related) and we are really close with them so I wanted to bring the baby over there to see my aunt and cousins (all in masks) and my husband gave me HELL over it . Everything’s fine no ones sick .

So tonight was his brothers birthday and we get to their house and his mom whispers to me that one of our nieces this week has had white spots on her tongue, redness in and around her mouth, teeth separating from gums and a fever.

She figured my SIL was going to tell us at the beach before we came over but I didn’t go to the beach, but my husband did.

My SIL had a teledoc with her pediatrician and he said he didn’t know what it was and put her on an antibiotic. But I feel that if she was unsure in this crazy time she should have told us and not had us over

I’m really calm and normally don’t stress bringing the baby places within reason, but this one has me seeing red.
