Hubs and I are more careful with our drinking water now that our twin grandchildren are staying with us. My husband read an article about infants being exposed to lead through drinking water. It’s scary because too much of this can lead to mental retardation. Besides that there are other things to be worried about such as chlorine, flouride, aluminum and nitrate. We only boil the water for the girls’ formula so hubs had decided to switch to reverse osmosis water filter. Apparently this filter will block common contaminants and give us cleaner water. Water is our main concern now that we have babies at home.
