I found that the disposable nappies were really expensive. As we lived in a remote area with no car access when our first child was born, we would have had to carry the new nappies up to the chalet each time to bring the waste back down. And since someone gave me a free box full of knitted nappies, muslin nappies, liners, some old AIO nappies and woollen overpants, I even saved on the purchase costs. So the goal of low cost was achieved.
After 6 months, I still used disposable nappies from time to time, especially on the road and at night. The knitted nappy system is great overall, but our daughter hated changing nappies. Because the old AIOs were slowly disintegrating and no longer sealed, I bought some modern nappies to test them.

When our daughter was 11 months old, I learned about Topffit/Diaper Free. At first I thought it was an American craze to get babies dry as quickly as possible. But when I understood that it was about something completely different, my husband and I gradually took our daughter out of nappies. Thanks to the cloth nappies, I already knew our daughter's rhythm very well. With the gauze nappies, which didn't have a stay-dry layer, she complained very quickly when she was wet. And suddenly I realised that I didn't just have to wait for her to wet her nappy, but could offer her the potty beforehand.

So we potty-trained our first son from birth. I continued to use the knitted nappies for protection. But it soon became clear that this system was too cumbersome for frequent dressing and undressing. So I developed my own system and the flopi came on the market after my third birth. With each child I used fewer disposable nappies and then stopped using them altogether. With the last children, I even ended up using nappies only at night (because I wasn't fast enough to get them to the potty in the morning).
