Today’s students were separate lessons of young girls. The pool was a bit cool and I was very happy to have with me a medium sized Warm Belly wetsuit. I found these wetsuits on the Internet and purchased different sizes on eBay. And they have come in handy. I suggest any toddler parent to buy a small for their baby. Pool temperatures are for those who are ACTIVE in the water. Often during instruction the student is still, listening to the instructor or at the wall working on an isolated piece of the stroke. Having that added insulation helps keep the student focused on the skill building.
