I'm not sure what the issue is because my AIOs are pretty much the same amount of absorbancy. I've got BFT, zorb, BFT, BFT, zorb, BFT, underneath OBV. I haven't gotten any reports of oversoaking/leaking issues with that on them from the people that have them at this point (I've got about 16 people now that have at least 2 AIOs from me, one with 12, which explains why I'm still behind stocking my store, LOL), and I know a few of the people commented that they've made it through 12-hour stretches or more overnight without leaking. I don't know if their kids are heavy wetters, light wetters, average wetters, et cetera though. I'm definitely wondering how I can make my AI2s more absorbant without being super bulky, which is what happens with the snap-in foldover inserts. I checked this on the size medium, and it's still REALLY bulky, and I assume it's because it's not more compressed from being sewn together into a one-layer soaker, which may end up making it thinner, but I'm not convinced the serger would be able to handle it too easily, although I can manage to zigzag okay with the regular sewing machine if I raise the presser foot height enough. My best idea for improving the absorbancy so far is to maybe have a small snap-on doubler for the crotch area. I think the main thing is that SS diapers are generally less absorbant because of the way they need to be made to be more trim through the crotch, although I'm convinced it would be better if I made it as an AIO style instead of an AI2 (which is still my preference). The other option would be to have the bottom layer of OBV, zorb, OBV, and then a foldover flap of like 2 BFT topped with OBV (I'd definitely have to play around with styling to make it look right, although I do have an idea that I could make it as two serged pieces and then just sew them together at the top and maybe bottom). My friend's heavy wetting just turned 10-month-old can only make it through about one pee with his SS diaper I gave her. If she lets it sit for his second pee it leaks a lot because there's nowhere for the extra pee to go and it tends to squish out the legs in the crotch area. Her almost 25-month-old does just fine with the lighter absorbancy of the non-foldover soaker, but had slight leakage at the legs, although the soaker isn't totally saturated. The only thing with her is that she's in the wrong size diaper because of how it seems to fit on her, like she would probably do a little better if she were in a size smaller as she's right in between sizes right now. Of course, her mother said she might need to just snap it on the tightest setting instead as she's had a bit of droopy diaper in it (so probably more of a fit-related leak I think?). Because of that, I'm actually a bit concerned that I need to resize the large again to somewhere in between my skinny-large and my normal-large, or shorten the wings a little bit on each end (the main place I adjusted besides adding length to the rise), so definitely something you'll all have to let me know. Like, maybe I should maybe make it somewhere in between the current large wing span and the skinny large wingspan, which would end up shortening and tightening up the waist about 2 more inches (I think). Oh, and I should hopefully be able to send out everyone's tester through a size medium by Saturday or Wednesday at the latest since I have a couple appointments between now and then. I've got the linings attached to the P/NB, XS, S, and about to put snaps on the lining of M, so right now so just need elastic, T&T, and snaps at this point. I just haven't received my order of OBV for the rest of the larges yet and I didn't have enough left over to cut out their linings too.
