County swim classes at Yorktown? I think it has the warmest of the three county pools.

all 4yr old classes are without parents unless you sign up for the specific preschooler and me ones, but those are really geared towards kids who have a major fear of the water and will absolutely not go in without parents

goldfish swim school or kids first

Preferably in Arlington, but willing to travel some. Looking to get a head start on summer. Can you recommend a warm indoor pool that offers swim lessons for a 4yo? Prefer kid in the water on their own, as I've heard this is the only way to get them to really learn to swim. Willing to do parent/child class too.
