Learn to swim Float suit
These float suits are a great way to assist your child in the water without using armbands, which can obstruct your child's arm movements. Each suit comes with 2 inflatable pouches, one in the front and one in the back. The amount of inflation can be varied, according to your child's needs, and can be reduced as your child progresses.
The sizes are small, but are marked as
Medium - marked 3-4 years 18-22Kg (the marking on the back of the pack actually says 3-6 years, but I estimate nearer 18-30 months )
Large - marked 4-5 years but I estimate nearer 2-4years
