We are on day 2 of a 12 day road trip. This morning when I got DD (20mo) when she cried she had puked all over herself and the bed. She does not have a fever and is acting fine. She has not thrown up since spitting up as a baby. She does sleep with two fingers in her mouth and lately has been trying to put her fist in her mouth. Thoughts? If we are all going to have the stomach flu I'd rather just head home.
