DS screamed like fuck in water when he was young and there was no way I was going to bother my arse taking a baby swimming for 30 minutes, enormous faff.
He started lessons at 5, he is now 7 and loves the water. Not that strong a swimmer but has great stamina and can jump in. He tries diving after seeing the Brat one from Minions (the 80s child star, 'i've been a bad boy!'. He'll hum thriller, do a little dance and bellyflop in
).
He has the winter off, but we'll start lessons again after Easter until the end of term. Then it's various pools and the sea until October!
I couldn't swim a width until I was 10, by 12yo I was on the school team specialising in backstroke. My dad has been a lifeguard, my mum can't swim, my sister isn't a very strong swimmer despite having a pool.
