@ellistonpediatrics: Babies and toddlers dehydrate dangerously fast. Their bodies are mostly water, but they have very small reserves — so vomiting and diarrhea can become serious within hours. One of the biggest risks: kids often stop drinking before parents realize how dehydrated they are. No tears. Dry mouth. Fewer wet diapers. Excessive sleepiness. Vomiting everything back up. And never assume another child’s experience predicts yours. Every child and every illness is different. . . . . . #dehydration #stomachvirus #pediatrics Best NYC pediatrician Manhattan pediatrician Brooklyn pediatrician
