Ds (just 4) has been swimming without armbands etc for almost a year, but hasn't been progressing very quickly. He can swim 5 metres easily, maybe a bit further.
He was given some flippers for his birthday and he loves them. He can easily swim 10 metres or more and they make it much easier for him to take a breath.
Any swimming teachers here who might know whether using flippers will help or hinder him in the long run? He doesn't wear them for the whole time we're in the pool.
Thanks.
