I have BBH nights. They're bulky, but overnight they don't even come close to leaking. And our wee poppet has them on for over 12 hours, and is a hardcore wetter.

Trim nappies... ittis are pretty trim. Bambootys (small fit) BBH petite all in twos. I find Bonnibuns quite trim, similar fit to CGRs, but a little bit firmer around the belly. The Genesa Forge side snaps are pretty trim too. Using pockets can be a good way to stay trim as you get to vary what's stuffed in there.

I find you get a better fit with sized nappies, but if $$$ are an issue, then OSFM naps are a good choice. GreenKids, Bonnibuns, Bubblebubs Candies, BBH Multifits are options you can use.

We have no issues with cloth because we just don't know any other way. We've used them right from the start. I cannot handle the thought of poo sitting in my bin. That's gross. Instead, poo gets dumped into the toilet, where it belongs, within 10 minutes of me changing it.
