Side Snap Onsies

I've been on the hunt...for the elusive side-snap onsie! Why is it that it is so hard to find?? Onesies are everywhere, they come in packs, like underwear. But they are all pullovers. I've heard that many parents of newborns have difficulties pulling a small onesie over their floppy newborn heads. It would appear that the side-snap or "kimono-style" onesies are a perfect solution for newborn attire. You can lay it open on a table, place the baby on top of it and wrap the baby up. Easy, simple, and eveyone's happy. But why has it been so hard for me to find these onesies?? When I do find one, they cost a ridiculous amount of money! Why are they not more popular and in demand?? The only place I found a 3-pack affordable set are here at Albee, they carry the Gerber side snap onesies. But they are out of stock!!! Please restock them!! I was planning on purchasing 6 0-6 month sizes for my baby's staple wardrobe.
