If breastfeeding, then after they start solids (around 6 months), if they are a bit constipated. And just a small quantity too, a few sips at a time. If not, breastmilk is sufficient as it very hydrating... just need to offer more feeds if baby feels thirsty
depends on ur baby whether is on breastmilk or FM. If breastmilk, no need to give water. But once the baby started on FM or solid food, yes u have to give water
