Playing devils advocate, I take chemotherapy by injection weekly, so immune system is weak. I have multiple issues so I have an illeostomy & im tube fed. So I don't go to a restaurant to eat but keep my hubby & children company.
If you were on the table next to me I'd be freaking out, DH would know I'm freaking out and start to panic himself as he knows what will be going through my mind. We protect the children from such fears as we don't want them getting a phobia of being ill.
I would then be on high alert for 72 hours, panicking at every creak of the floor boards after bed time, panicking everytime someone went to the loo at night.
If I was to fall ill I'm pretty much guaranteed a hospital admission. Depending on how bad the issues.
At 12 months you have spit ups after feeds, then you have actual vomiting & if it covers you, your DH & baby, plus a sizeable portion of the room, that is code for baby has a bug, stay indoors or make your way home. Try to have as little contact with others as possible. Get a container or something so the person sat with DC can catch the sick.
It is my number one pet hate, hearing kids who are out saying they don't feel well, then throwing up over half the restaurant. It doesn't do good for other patrons who suddenly won't be hungry, plus the poor staff are at risk as well.
But you have the added pleasure it appears, of not ONLY infecting the restaurant but a plane too.
We bash MIL's but we would certainly not take a child into a public place and risk others safety. It seems that we didn't do the initial what a bitch MIL for not cleaning clothes, so now it's her fault for you infecting a restaurant with a sickness bug that is going to can their livelihood.
What's the betting MIL calls with, oh that restaurant we went to was on the front of the local paper after everyone got sick. Good bye business reputation.
