For the first six months, newborn should be exclusively breastfeed. This means even water is not allowed to be given to the newborn.
If you feed your baby with formula milk, no water should be given as well. You should follow the recommended ratio of water to formula milk given by the manufacturer.
Water can be given once your baby starts to eat solid food.
