Where do I put baby while child is in swimming lessons if pushchairs aren't allowed poolside

[Learnthroughplay3]

My child is at swimming lessons but im pretty sure prams aren't allowed at pool so what do you do with baby whole swimming lesson and while you are sorting child out before and after?? I have had this situation before but can not remember what I did with baby

I take my twins poolside in the pram because the viewing gallery is upstairs. I rang the pool in advance to see if they could accommodate me. I take my 7yo with swimmers on so he just strips off poolside and passes me his clothes. He's just started to go and get changed afterwards himself but we did a course of intensive lessons in the summer and I just helped him poolside and held the towel up while he got dressed.
