I wanted to feed baby water, do I give normal water or warm water? Need to buy extra milk bottle for drinking water? What kind of milk bottle to choose to feed water?

Below 6 mths, you won't be feeding a lot of water, i will use spoon feed or small transparent cup for feeding water. After 6 months, do start with straw bottles instead of sippy cup. I feel sippy cup is waste of money, my kids nv get to drink any water from it.
