Not sure what to do about the ones DS has just started. He went to some a 20 minute drive away that I have been very happy with. They were teaching him using a swim fin. When he turned up at his new lessons he had his swim fin but they took it off after 5 minutes and put arm bands.
Firstly the swim fin was £20 so I would it to be used.
Secondly we told to get the swim fin cos it gives the best body position in the water and doesn't affect arm movement like arm bands do.
Should I mention it or just let them get on with it?
