Best “puddle jumpers” for two year old?

Hey friends! We spend a lot of time at the pool. I have three older kids, and my two year old. My two year old often wants to be in the deeper end with her siblings (assisted and supervised, of course) so I’m looking for something comfortable, that would keep her afloat as she hops in from the side, paddles from person to person, etc. It’s been a LOOONG time since I bought floatation suits for little ones. Amazon is inundated with options and it’s overwhelming-so I’m hoping for first person experiences. Thanks in advance!!
