How many session to learn breaststroke kick for a 7-year-old child?My son has done 19 group sessions of breaststroke.He is on stingray level. Just wondering how many more to go? It's costing a lot and wondering if it will go up to 50 or more sessions to learn breaststroke?Is this normal to have this many sessions and not move up a level? How many sessions did it take your child to learn breaststroke kick?
