This is a really tough decision for me, and after thinking about it for a whole morning, I still can't decide, and am coming to the internet for help.
A month or two ago, I bought these:
NorthShore Care Supply: Tranquility ATN Briefs - Youth Sizes
When deciding what size to purchase, I amateurly measured my waistline and found myself to be 32".
"What luck!" I thought to myself, seeing that that is the exact measurement that allows one to fit in both Small and Medium sizes. I went with Small for being cheaper.
When I tried one on, I found out that it just barely fit me. As in, if I were an inch fatter, taping it on would be impossible. So it turns out the measurements they provide online are as exact as can be.
Knowing this, my next purchase from the Tranquility company has put me up to make a very tough decision. I now want their premium OverNight pull-ons:
NorthShore Care Supply - Home Care Products and Scales
Small is 22" to 36", which would definitely fit me, and Medium is 34" to 48".
Ooh... it makes me wonder, will Small be a little tight? Medium will of course be a little loose, but would it be too loose? If I had to choose between tightness and looseness, I'd pick the former. Buuuuut...
Small absorbs up to 20oz of fluid, while Medium absorbs up to 34oz!
When I wet my ATN briefs as much as I could in one usage, it DID leak a tiny little bit, and I'm sure would leak more if I wet it more. And they hold 22oz. So if I bought Small pull-ons, I'd definitely get a few leaks. But Medium, if it fit properly enough, could hold more than I'd ever need.
So my question is, which size should I buy?
One alternative I have thought-up is to buy Medium ATN briefs, and then buy some booster pads along with them; I'd really like to try the pull-up kinds, but this will definitely fit me and give me ultra-mega absorbency.
