Practice makes perfect! There are various kinds of cloth nappies available (in various sizes) but most of them either have a waterproof backing or separate waterproof cover and fasten with either poppers or Velcro® and can be used with biodegradable, flushable nappy liners.
The actual nappy changing process is the same as with disposable nappies but it’s a good idea to have a pile of ready-folded nappies ready so you don’t have to think about where the folds should be while your baby is wriggling about!
Nappies should be washed in the washing machine at 60oC. However, there are nappy laundering services in many areas, which replace soiled nappies with freshly-laundered nappies every week.
