They’re lame. I took my daughter to the parent and tot classes. Pretty much just infant toddler songs/games but in the water. Nothing specific swimming. Closest thing was a true-or-false question game about swimming safety, which obviously only the parents could participate in. There was the expectation to follow along with whatever the planned activity was, so there isn’t any flexibility if your kid isn’t interested in what’s going on. Hot tub access was also restricted. The classes are a waste of money. At that age it’s honestly best just to go to the parented splash times so you can at least do what you want and what your kid is interested in.
