Keep in mind that it requires more than just a few episodes of vomiting or diarrhea for an otherwise-healthy child to become truly dehydated. Signs of dehydration to monitor for: dry or sticky mouth, lack of tears with crying, sunken “soft spot” in babies, not having any urine output for > 6-8hrs, lethargy. Bear in mind that if your child is <6mo, dehydration can occur more quickly.
I'm worried my child will get dehydrated. What should I look for?
