I didn't in end because couldn't get class I wanted but the plan was made with another parent of two children that I would look after e.g watch in pram her youngest while she went in and then vice versa for mine. As lessons only half an hour we thought would work fine. I could see the baby at all times so would have been able to get out if got mega distressed etc. To be honest I didn't really understand why someone had to be poolside with pram as baby restrained often asleep etc. But that was not encouraged.
