Our 10 month old baby has a few (maybe 5) little red dots on her skin, they look like pimples, and tonight, she threw up. She otherwise acted normally (ate fine, wasn t running a fever, not irritable or overly drowsy). However, we ve noticed that what started as one pimple has expanded to about 5 in the last few days. They are in different places on the body (arm, leg, face, hand). We recently came back from Cancun and we had bug bites, but baby didn t seem to have any. Don t know if this is relevant, but I thought I d mention it. thanks!
