I would love for my Taggart to learn how to like water too. My boy is so finicky that he doesn't even step in puddles, lol.

Anyway, Taz_Zoee's suggestion is probably the way to go. Especially keeping the kiddie pool available.
I would not try and get her into deeper and colder water just yet (beaches, lakes etc.) considering she's so young and you definitely do not want her to have a bad experience with water at this age
