To puddle jump or not. I’m on the fence I have recommended them in the past but she makes so really good points. I still like them and will use them, but they can give parents and students a false sense of confidence. We always have to be super aware.
I watched this video this morning, It was recommended to me because we are part of the Kelsey Kode. 
Through The Kelsey Kode, you have the ability to learn from some of the industry leaders and to quickly and easily tell thousands of other members about who you are and your Company, Business, and Organization, how you provide solutions to the problem giving you the opportunity to educate people.
I run a swim school in Marin County, Ca. and an Master in my field. While my method of survival teaching varies from hers the idea is the same. Help kids to survive in the water by teaching skills that help them roll for a breathe. Which requires them to have their ears in the water. 
As you can see from the video the baby crys a little, a wimper really. That’s a good sign believe it or not. Crying for a baby in the pool is an alarm. You would rather hear your child cry instead of not crying. Most parents can’t stand to hear their children cry and will pull them from lessons saying they will bring them back when their “more ready”. Just like learning to crossing the street , it takes practice. Little kids are not known for good listening skills. More ready is now. Here’s a video of my swim swim roll skill set from a few years ago.
As lifeguard trainer for 20 years and a swim instructor for 30 + years, teaching is my mission in life. I have kids start at 3 months just 10 minutes a couple of times a week. We practice 3 skills sets 10 times in private lessons.
Tips for getting kids used to water in their face before putting them into a pool.
- Putting children in the shower is great way to get them used to water on their face. I had 4 children is 5 years so If i took a shower most of the kids where in with me or just in the bathroom. I had the bath chairs that suctioned to the bottom of the tube and give them toys to play with.
- Putting googles on them in the house, Call them bravery glasses or magic.
- Use a mirrior with your child so they can practice closing their mouth, some kids are copy cat learners. So my turn your turn works well.
If your child is fearful of going under follow up here. I believe everyone can learn to swim. For more information on missjeanswimming check out my facebook page.
