When we first put it on him he flopped over like a cat does. ??? Then he finally stood up.
Hahahha.. sorry the visual is funny:)
We have one just like it for Bava , He is a little freaked by the ripping velcro sound when we take it off, but otherwise it is great. I love it because it keeps his head higher out of the water... That means less water in his ears, he does tend to get ear infections easily, and less chance of water in his lungs.
He got used to it pretty quickly and when taking him with us canoeing, he figured out he didn't have to swim and would just kinda float around and give a lazy kick every now and then, it was pretty funny.
Not the greatest picture I know, but you can see how much higher his head is out of the water, and his ears are out, where they are pretty submerged without the vest.
Here he is without the vest:
And with the vest:
