5 Ways to Tell If Your Baby Is Getting Enough Fluids

Observe urine output and color. If your baby’s diaper is wet at least 6–8 times a day, and the urine is light yellow and odorless, it means your baby is likely getting enough fluids.
Pay attention to your baby’s general behavior. If your baby is alert, active, and content, they are probably well-hydrated. Signs of dehydration may include irritability, lethargy, excessive sleepiness, or persistent crying.
Check the moisture of the mouth and elasticity of the skin. A moist mouth and tongue, along with skin that looks firm, elastic, and smooth, are good signs of adequate hydration. If you gently pinch the skin and it returns to normal quickly, hydration is likely sufficient. Dry, cracked lips or skin that lacks elasticity may indicate dehydration.
Feeding frequency is a key indicator. If your baby seems relaxed and satisfied after each breastfeeding session and stops nursing on their own, it’s usually a sign they’ve had enough milk and fluids.
Monitor weight gain. Regular weight gain is generally a good indicator that your baby is getting enough nutrition and fluids. If your baby’s weight gain slows down or stops, consult a pediatrician as soon as possible.
