Recommendations? She's 15 months, walking/running well, so nothing so terribly bulky that it hinders her more than it helps her. But i want to be able to not obsessively hover over her and let her wander in the water a little on her own, or take her into some deeper water and not have to worry about dropping her. Lucie's list recommended this one: http://www.amazon.com/Stohlquist-Infant-Nemo-Personal-Floatation/dp/B005T9GLRS/ref=sr_1_cc_1?s=aps&ie=UTF8&qid=1404133406&sr=1-1-catcorr&keywords=stohlquist+life+jacket+infant

has anyone used it? thanks!
