I planned to start after a week or 2.....but after a section, a lot of problems with feeding and OH starting a job when LO was 5 weeks old (which was a good thing, but took away a lot of my support) we didn't get started with the cloth until last week, when LO was 11 weeks old.
I kept saying "I'm top busy to start with cloth, I can't leave LO for a minute without crying so won't have time to wash nappies, I spend all day feeding"...then I just thought I need to stop making excuses and just get on with it, and tbh its been really easy. We are still using disposables for night time and for going out and this combination means I don't really notice the extra work of washing nappies. It's actually been really easy.
