I've been testing OS dipes lately, and I have to say that my favorite at this point are Muttaquin 3SR and Bububebe. They both fit my ultra-skinny little guy, they both work overnight (first ones I've found that will hold everything overnight), and because the rise snaps down instead of folds down, daddy could even use these (he can't figure out the ones with the fold-down rise).
I do also really like Bag Shot Row Bamboo and Goodmama, but they are both fold-down and neither will last through the night. My Sustainable Babyish OS pin dipe is also lovely, but because it doesn't even fold down it's difficult to cover - I have to size up in wool to cover the high rise. All of these fit beautifully, but they will not get us through the night, and none of them can daddy figure out.
