Now that I've had a chance to try them I can add to this!! We're still in early days but Lucas has been a cloth bum since birth!
So far he's mostly worn Teenyfits. They're lovely and slim, but don't sit under his cord at all, they go quite high actually! Doesn't seem to be a problem yet and hoping cord will go soon.
The Lil Joeys are good, they sit almost under the cord on him and are slim between the legs but "thick" with material and not as high in the rise as a Teenyfit. They won't last as long but was a great first nappy.
The xs OWW was a lovely fit and sat well under his cord. The wool wrap went over it though! Lucas was 7lb 11oz born and 7lb 3oz an hour ago. He's very skinny though and doesn't seem to have a lot of length between belly button and bits - a long upper body though! Going to play around with the nb swaddlebees, kissaluvs, xs sandies over the next day or so with various soakers/wraps and will take pics and report back in time.
He's still not pooing lots so I'm not getting through as many nappies (yet!)
