My mum was similar, she had 3 in terries but has always been nervous of ' new cloth' I think just due to practise. She also lives far away so didn t have chance to practise. We used a prefold system only with dd1 and she worried about getting it on correctly.
She's happy happy with pockets now .... I say now but we ve just potty trained dd2.
My Mil told every man and his dog all about us using cloth and ' how it's come on' since the olden days
She's a kind of ' your the parents i ll go along with what you want me to do'
I think cloth confuses people, understandly so sometimes. If you re using two parters it's the same kind of principle to get her head around, soaking uppy bit then waterproof cover.
Still lots of misconceptions about, some people still think you ve got to boil them!!!!!
