I use pockets a lot (although I do love fitteds too, especially with newborn bf poo!). I don't have a tumble drier so being able to pull them all apart to dry in doors on a clothes horse at this time of year is invaluable! My fitted nappies take nearly twice as long to dry
I use LL BTP pockets and Charlie Banana one size pockets (Fuzzibunz didn't work for me at all). I must say that when she was very young I did get leaks a lot more often which very rarely happens now unless she's accidentally left in too long. I think this was possibly a fit issue and that's why it doesn't happen now that she's bigger (a chunky 9 month old
I seem to have a heavy wetter so soon discarded Microfibre inserts as they didn't seem to work at all. I use 2 bamboo (mainly the LL bamboo that come with the pocket nappy) and then 1 hemp insert underneath (furthest away from bum iyswim). This generally gives me 2.5 - 3 hours. Not everyone seems to get on with LL pockets but they work really well for my LO. They do have sized ones as well so maybe try a small one to see if you get a better fit with that?

I have just bought a GroVia AI2, so it's a BTP shell with a hemp/cotton insert that snaps in rather than having to stuff the pocket. Haven't tried it yet though as just finished drying from being pre-washed but I'm hoping this will be another good one as seems quick to dry and should be very absorbent being mainly hemp
