We went to the slightly-further-away council place because it has a baby pool and just had a bob about. I thought he'd howl within a minute but he stayed calm for 25! We even got a couple of smiles :o i think he'd have tolerated longer but his hands were turning purple and his teeth gums were chattering. He didn't yell till we tried to dress him, even under the shower!
I won't be signing up for lessons yet, but then my friend I've been going with for years pre dc is a swimming teacher, so we'll just carry on but with her toddler and R. More bubbles, fewer lengths 
Speaking of which, i haven't seen bubbless or gilsbubbles for a while, plus countless others whose names i can't remember off the top of my head. Hope everyone made it through ok...
