Well, semi-organized playtime in the pool might be more accurate.
Yesterday morning Rebecca and I went to the Plant Bath for her toddler swimming lessons.
She was about the biggest kid there, but she didn't use the opportunity to rub it in the faces of the younger kids or anything. Besides, she was having too much fun splashing, floating on her front and back, and having water poured on her head while myself and all the other parents (erm, mothers would be more precise) sang nursery songs.
Quite fun, I think we'll go back. ;) (We're signed up for a session)
The session didn't last too long, which I suppose is good. I'm not sure who would tire first, the toddlers or parents.
