We've got 3 in rotation:
A First Class Baby Nightlight - but the elastic has just gone in it! Oh, NO!!!! After only 4 or 5 months. This was a super duper diaper, but she always does a poo first thing in the morning, and now it comes out the legs onto the wool cover. I'm gutted over losing this one. I was a tester, so I didnt buy it, and dont know whether to mention it to them or not.
A Little Caboose fitted - this is fabbo, very well fitting and very absorbent with the doubler
A Happy Hempy - this one is in no way pretty and its gotten very scratchy, but its an extremely effective without being too bulky diaper. But the velcro's wearing out fast.
