Best armbands/swim jacket for 4 year old?

[turtleturtle]

What arm bands or swim jacket would you recommend for a 4 year old to build confidence and have fun in the pool?
We are going to start taking him more regularly!

None. Find a pool where they are not out of their depth and stay close.

Neither. A pool noodle under the armpits will keep him in a more natural swimming position. You can also sit on it like a horse. Have a Google you will find lots of good ways to use a pool noodle.
Also spend loads of time in water he can stand up in getting him used to walking around in the water getting gradually deeper and deeper.

We thought about a noodle! Might give that a go instead then :)
