Sparkly water feels like it doesn't want to be drunk.
It is funny, I love carbonated drinks, but when my daughter was about 2 or 3 years old, we were out somewhere and people were drinking soft drinks. She wanted to taste Sprite so we gave her a glass. She took a sip, made a face, and started sticking her tongue out and going "ugh ugh"
We asked what was the matter and she said "it makes my mouth feel .... so .... so .... sprite" and she has never liked carbonated drinks since. Not soft drinks, sparkling water, not beer, none of them. In college, she spent a summer in France and her 3-4 main companions all liked champagne so she drank that fairly often with them, and tolerated it, but still didn't like the carbonation.
