Yup we had some stomach bug that made its rounds in our house, right after Thanksgiving. Then again, this is the first year my kids have been in a nursery/preschool setting. Hit my 15 month old first--3 days later my 3 yr old--24hrs later my hubby-- and then I got it a couple days after.
It was horrible, not so much the throwing up, but the day after was the worst. I had this god awful headache and my body just ached to the bone. I had to call the hubby to come home and watch the kiddos. I just couldn't do it. Luckily it didn't seem to hit the kids that hard. And as it seemed to have only lasted 24-48hrs between each of us.
Good Luck I hope you feel better soon!
