That is some good advice, thanks! But,
Well,.... Uni's never been in the pool. We took her to the beach a few weeks ago, and I want to get her a life vest for the future (for the beach). So I don't really know.
We tried to teach her to swim when she was a baby in our tub. that's how small she was. We haven't tried anything aquatic since the Coronado thing.
Uni's measurements is what is throwing me off. She is tall ( in the legs) but thin in girth, but light in overall weight.
