Hmm..I like the bummis better just because of the gussets.

Baby Beehinds are quite large sizing - the small is still a bit too big for Miss M, but the Bummi's smalls fit fine.

I prefer the mother ease covers - they have the gussets and are easily adjustable and their size ranges are brilliant. I had Miss M in a newborn, then jumped straight to a medium with those.

I think I have 2 motherease (medium), 1 swaddlebees (small), 2 bummis (one fleece and one PUL - both smalls) and then I have 2 fleecy covers from Maz and about 3 wool ones.

I've also put her in a Sugarpeas woollen cover tonight which is a medium but fits fine over her night nappy.

With this collection - I never run out of covers

HTH!!!
