Cloth bum mum here. I first used them with my eldest because my sister and sister in law were using them and I felt the need to join in! Soon fell in love with the patterns etc.
When my youngest came along in july 2019 I’d already decided to cloth bum, but only part time. I’d also worked out which brands I preferred. I never bought newborn ones, so only started her off once she was 6monthish. She was doing about 3 days in cloth, 4 out. Then lock down happened and there was nothing else to do and nowhere to go to worry about on time changes etc so she’s a full time cloth bum! Well, nearly - Days only, and her nursery won’t do cloth.
I’d say you won’t save money if you buy the expensive brands, I like close pop-ins, but they’re between £15-£20 a go for new. I’m not keen on buying used because the elastic can be a bit rubbish and then you get leaks.
You need to be aware of changing them nice and frequently. That’s no issue with a tiny as they poo all the time, but My two both seem to go once a day once weaned. I reckon on changing her every 3-4 hours or she’ll leak (or ‘out wee’ as we call it !) as she’s good at drinking.
As others have said, the washing really isn’t onerous. I wash every 3 days, if you part time cloth don’t leave nappies longer than this before you wash them or they can get stinky.
Enjoy your cloth journey!
