I like '2 part nappies' - nappies with a separate outer wrap - because they are two layers of defence against leaks. We virtually never get the poosplosions onto clothes that we had with disposables, and never get wee leaks. Also the wraps are cute and work as shorts in summer. Microfibre nappies suit us as they are super quick drying - almost dry when they come out of the machine. It was important to us to use as little extra energy as possible so we definitely didn't want to have to turn on a heater or invest in a tumble dryer.
At night we use the same Motherease wraps but with Bamboozle stretch bamboo nappies as these are more absorbent, they easily do the whole night with no leaks (when our baby is older we may need to add an extra insert for nighttime absorbency).
Altogether we have 15 Teddys, 6 Motherease wraps and 5 Bamboozle stretch nappies. The nappies are all birth-potty training but the wraps do come in different sizes so we had to rebuy these as our son grew.
