Right my DS (23 months) is starting swimming lessons at a pool where the temp is going to be 30°, I have been told by the company running the lessons that DS NEEDS (their capitals, underline AND bold!) either a wetsuit or a snugg (which of course they sell), am I being unreasonable to think this is complete bollocks and it's just another way for the company to make money out of us? Surely 30° is warm enough for a 23 month old to tolerate for 30minutes without suffering from hypothermia?
