I've googled but everything seems to be about taking babies (tiny ones!) swimming for the first time.
I literally cannot remember the last time I set foot in a swimming pool, I'm taking my very nearly 2yr old today just him and I because I like to make things difficult for myself 
Any tips to make it easier or etiquette I should know about? There's a lot of threads about changing rooms on here and I'd rather not do the wrong thing in RL....
Can I leave a towel on the side to bundle him up as soon as we get out? Can I take a small ball for him to play with?
Literally any advice appreciated
