infants are more likely to become dehydrated than adults
If your baby's dehydrated, it means that she doesn't have as much fluid in her body as she needs. Babies and children are more prone to dehydration than adults, and it can happen if your baby takes in less fluid than she loses through vomiting, diarrhea, fever, or sweating. Dehydration can be mild and easily corrected, moderate, or severe and life threatening.
