What do I do?!?!

Samantha

We’ve got some sort of stomach virus in our house right now and I’m completely terrified that my 3 week old will get it! My 3 year old started at 5 this morning with throwing up then by 11am my 8 year started throwing up. They both can’t keep anything down they’re very tired and just worn out. No fever just throwing up.. what should I do?!
