My baby is scared to death of pools and the ocean. Guess where we are heading in a couple of weeks?

So I need advice of some fun or just plain functional flotation devices to try to get her used to the water in a non threatening way. She is 30 lb, so most infant floats are no longer an option, though she would fit into one without a problem. What do you like?
Re: Pool floats?
Last summer, C liked Swimmies (the inflatable arm bands) and this: https://www.amazon.com/Swimways-Baby-Spring-Float-Canopy/dp/B00253T7R2/ref=sr_1_fkmr0_1?ie=UTF8&qid=1305599264&sr=8-1-fkmr0. She also really liked this cheap-o blow up float that looked like a pink car with a steering wheel and horn that I got at kmart.
When we took swim classes a couple months ago, she just liked using me as a floatation device along with a noodle.
I would bring a few different things along to see what she likes. GL!
You can take me instead!
I would get a life jacket.
