Breast milk or formula is a complete source of hydration for newborns. Make sure to feed your baby on demand, which means whenever they show signs of hunger, such as lip smacking, sucking on hands, increased fussiness, or restlessness.

Keeping track of your baby's wet diapers is a good indicator of their hydration. In the first few days, you can expect at least one wet diaper for each day of life (1 wet diaper on day 1, 2 wet diapers on day 2, and so on). After that, your baby should have about 6 wet diapers a day.

Ensure that your baby's environment is at a comfortable temperature. Overheating can lead to excessive sweating and potential dehydration.

If you're breastfeeding, remember that your hydration affects your breast milk's quality and quantity. Drink plenty of water throughout the day to support you and your baby.

If you're formula feeding, follow the instructions on the formula packaging for proper mixing and dilution. Avoid giving water to your baby unless your healthcare provider advises it.

Consult your pediatrician if you have concerns about your baby's hydration, weight gain, or feeding patterns.
