Do you bring your 5 mth old LO to swim? if yes, pls share where and if the pool is dechlorinated and heated?

I bring my LO to swim at condo pool since 4 month old n he swims at least once weekly. My boy is attending lessons at little splashes swim school (mineral water) but little splashes only accept students from 6 months onwards. N I would say non chlorininated water is necessary because they let the baby go into the water fully from the first lesson. So better for the eyes. But if there is no intention of letting your LO go into the water but just relaxing swim, a normal pool will do
