My baby boy has been sick since his first 3 days at daycare last week. He has been vomiting once a day since Friday, didn’t last night. (although Friday was twice a day). No fever, has seemed happy, tonight he vomited again so I checked his temp. 100.8. Gave him Tylenol, he gagged, vomited again. I am a FTM so I’m freaked out. Any tips?
