Round Rock Rec - Clay Madsen - has swim lessons going on btwn now and then. (www.roundrocktexas.gov) click on recreation, then clay madsen - you can view the schedule online.
My little ones loved these classes! Its a mommy (or daddy) and baby class, so you'll get in the water together (FYI) and it's indoors now until late May/early June.
BTW, my both of mine were swimming before 2(by that I mean I could let them go and they could swim to the edge of the pool and hold on, or swim to another adult approx 6 feet or so away - they're not like competing in the Olympics or anything! lol!) and I credit that to these classes. I thought the instructors were great and the games we learned in these classes are still played in our bathtub each night! :)
