DD is 14 months old and will be starting weekly swim lessons in June. What do I need to know?

Please share your swim diaper recommendations. I'm wondering about disposable v. reusable. Wondering about the iPlay reusable specifically. Other specific brand recommendations would be helpful!

Anything else I should consider? I'm hoping to quick shower her off with soap and lotion her up while we're there since she's an eczema baby. Also bringing a big, fluffy towel.

If your kid has ear tubes, do you use plugs in the pool? We were advised not necessary in the bath, but I'm unsure about the pool.

Thank you!
