looking for infant swim diaper

[downvalleygirl]

i'm looking for a diaper that will fit a 5 month old and will hopefully be able to span several months after that.  a diaper that's got good seal around the thighs and maybe even a top to protect from wind and sun?  

thank you!

we have this one http://www.imsevimse.us/p-129-swim-diapers.aspx

it fit pretty well this summer, though we never had a dirty in it. DD has a small, as she was 15-17.lbs over the summer. it might still fit her now at 21 lbs, but she's long and skinny.
