According to some mommies, distilled is adviseable to use for up to 2years of age, since wala silang minerals that causes reaction sa formula milk, and also kaya distilled muna for this age kasi hindi napprocess ng katawan ng bata ang mga minerals na nakukuha sa purified/mineral water. After 2years pwede na iintroduce ang kids sa purified or mineral water. And about sa anti-bodies, they get all the anti-bodies they need sa breastmilk.
