When I went over to cloth nappies, I was very sure on one thing: I wasn't going to use the all-in-one (AIO) type nappies. I had heard that they were very leaky, and also they were more expensive, didn't wear as well and took longer to dry. I still feel the same way about AIOs, but have had to admit that perhaps they are a necessary evil in certain circumstances. Having two babies in nappies now, I have taken the plunge and bought them an AIO each, but only for when other people are looking after them. I bought a Kooshies Ultra for my son, partly because he is (hopefully!) close to potty training, but mostly because I needed it in a hurry so his nursery would stop sending him home in a disposable which was causing him nappy rash. I have to say that I'm not all that impressed with it, as it lives up to its reputation of being leaky and it isn't breathable. With more time to choose, I bought a Motherease AIO for my infant son, and have to say that I was very impressed. In spite of his explosive breastfed bowel offerings, I have found it very reliable. It washes well, dries relatively quickly (for an AIO), and has the same breathable outer layer which has proved so popular on the Motherease Rikki and Airflow wraps. I still wouldn't use an AIO on a regular basis, but there is no doubt that they are convenient for babysitters and childcarers, and the Motherease AIO is very impressive indeed.
