I've had to change my children's swimming lessons as the pool where they were going has closed. There's a different pool that I can take them to for their lessons, but I have a feeling that my youngest (he's nearly 5) won't be able to touch the bottom. He's been having lessons since July, but he definitely can't swim. I'm just wondering, do you think this would work? How do they teach them to swim if a child can't touch the bottom? The lessons will be 2:1, so one instructor for my 2 children. I'm just wondering how this would work when the instructor is working with my other child.
