DS doesn't like sparkling water; however, when he got sick this fall with a stomach bug, he started drinking soda. Before that he didn't like the carbonation. He doesn't drink much of it. Usually only at the movies or if his stomach is upset. I have a Soda Stream machine that I use to make sparkling water for myself and the soda syrups that come with it are fairly low in sugar. Actually if DS requests I make him some, I don't tell him it's actually diet.
