All of them are holding up pretty nicely, we've never experienced a diaper leak or a bum rash.
If at first I was happy to share my enthusiasm for cloth, now am I surely singing in praise.
The few times we had to use throw-aways (pampers and libero) not only did we have to clean up pooped clothes but also there was something very wrong with the smell...
Pee smells like burned rubber and poo always smells much stronger than in cloth diapers.
The 6 months mark:
pop-in by close parent The bamboo edition is still going strong although when I first got them they looked frail. Works wonder in the summer, but I wouldn't recommend bamboo for colder climates as they take more time to dry.
oh katy Still my favorite kind of pocket style microfiber. The inserts are still very absorbent and they have little extra buttons that helped the first months.
blueberry Minky shell are soft but I don't recommend them for warmer climates. The most expensive but great quality inserts.
happy heinys maybe the best microfiber inserts of the lot... after everyday washing for months they still absorb like new...
fuzzibunz The waterproof fabric looked thin but to date they are still going strong.
rumparooz while big for a newborn, great for a 6 month old as the insert shape isn't rectangular but is "shaved" on the sides reducing the bulk around the legs.
bumgenius still my least favorites... The only ones of the bunch I wouldn't buy again. The inserts have become super thin and don't absorb anything anymore.
Lastly GroVia have retreated to the back of the shelf as they still take forever to dry (in 38c summer!)
My six month old uses around 4-6 diapers per 24 hours. One of them at night.
