I took pictures for this post, but unfortunately photobucket is loading really slowly today, so I'm just going to have to explain it the best I can and link to other pictures. Sorry for the inconvenience. Click on the links if you don't understand something I'm saying.
I love my Snappis,which keep me from worrying about poking Doodlebug with a diaper pin, but I will admit I have had a couple of problems with them. Here is how I solved them.
The middle claw gets in the way.
It just dangled there. I never could get the thing to truly hook on so it wouldn't come off. The directions say not to cut it or you will weaken it. So I didn't. But you can very easily pry the hard plastic claw out of the rubbery plastic so it won't poke. My Snappis just have a dangly piece in the middle with no claw, but it doesn't get in the way.
I am using cheap diapers and the Snappi pokes through.
I use Gerber prefold diapers, which are very thin and don't work so well with a Snappi. I thought I was doomed to diaper pins until I discovered the safety feature on the new Snappis. You know the little round tab on the top? When they aren't being used this pulls down over the claws to prevent poking. I pulled it down (see the second picture here) and just use it like this. It makes it not poke down so deep so it doesn't go through the diapers. You absolutely HAVE to use a diaper cover if you do this, though, because the corners of the claw are exposed.
Hopefully that made some semblance of sense with no pics. If you have a cloth diapering problem or solution, let me know. I'd be glad for the wisdom and would love to share what you know!
