Summer swimwear ?

Hi! My 16 month old loves water and did great in the pool and ocean last year. We are looking into swimwear that she can wear without us holding her in the pool. We will still be a reach away but we want to give her a little more independence to attempt swimming. Life vests are harder to find for 18-24 month olds and she isn’t heavy enough for a lot of other vests (currently around 22 pounds). Any ideas or advice would be great! Summer will be here soon enough I hope 🤞😀
