Just in case everyone didn't see my reply in the gas thread.
We use the Windi to help DD with her gas. It works great! You have to massage their belly like it says in the instructions and it works well. Took me a couple times to get the massage down. Also, lifting her legs to different degrees helps too and sometimes the amount of catheter that is inserted varies. Also, sometimes taking it out and re-massaging and then reinserting needs to be done a few times to get all the gas.
Just be careful--it can cause LO to poop too. We had poopslosion here the other night. Literally poop shot out her bum a few feet. Poop was everywhere. But yeah, this thing works really well and the relief I see on DD's face is pretty instant.
