MM, if you are looking for the cloth alternative to a sposie (which is what i was), then i found pocket nappies to be the best, just put on like a regular sposie, no worries. I bought fitted nappies and TBH, they are bulky and i cant be bothered putting a cover on, to me its like putting on 2 nappys at once KWIM?.
But fitted do tend to offer a better seal around the legs and with a cover last longer than pockets or AI1/2s.
My kid generally poops once a day and its rarely really ugly so pockets work for us and they are the easiest to get your head around (and DH's and daycare/grandma ect....)
Having said all of this, I am assuming you are buying for Mia, not a n/b, that would be a whole different story......
