Dehydration in babies can develop quickly. Key warning signs include fewer wet diapers than usual (significantly less than 6 per day after the first few days), dry mouth and lips, unusually sunken soft spot (fontanelle), lethargy, and decreased tear production when crying.
Other indicators:
If you suspect dehydration, offer frequent breastfeeds or formula in small amounts and seek prompt medical advice. For babies under 3 months or those showing severe signs (very low urine output, extreme sleepiness, rapid breathing), go to urgent care or the emergency room. Early medical evaluation helps prevent complications and may require oral rehydration solutions or intravenous fluids.
