I used reusable and had three in them at once. It was three extra wash loads a week. That's it.
I started off with terry squares and plastic pants, then Motherease shaped nappies and wraps and then tots bots. I used grippers with the squares rather than pins and had thicker nappies lined with pads for night time.
I had two nappy buckets and also used washable wipes for a time.
No extra work, no annoyance at a clean nappy being filled in seconds, it isn't hard to put a wash on. I just roll my eyes at all the extra work when it is just like washing clothes. Dirty nappies in a bucket. Dirty clothes in a basket. Pick up, put in washer, add detergent, soap nuts, turn on. Peg out, fold, put away.
We had disposables for the first couple of weeks as baby was small and then bought maybe six packs over the time of wearing nappies for emergencies when staying away or to leave in the car. I would make up the washable with their cloth liner then paper liner and also had a wipeable bag for dirty nappies.
