I like the way you describe it "weaning into cloth" - that's what I did but I didn't know to describe it that way!
I found a couple of things helpful.
1. When just starting out, I did only one diaper change in cloth per day, in other words, two cloth diapers a day. After I got comfortable reading the signals so to speak from the cloth (rash issues here too), I went to all cloth in the afternoons (we generally go out in the mornings and are home in the afternoons). Then I added mornings, and then nights. Each time I allowed time for a learning curve on pee, poop, laundry, and at night time, sheet and mattress cover laundry issues. It took me four months (with twins mind you so it might take much less time with one :LOL ). I've now been in cloth for 4 months and will never go back to sposies!!!!
2. I switched from sposies to pockets, using some Fuzzi Bunz and some Wonderoos. I found this the easiest switch because it involved the same length of time per diaper change as sposies, and the same basic strategy (using snaps instead of aplix but you KWIM). No two-step process, pins, snappis, etc. The other thing was the pockets kept the girls dry like the sposies, no clammy butts. I'm not opposed to other diapering systems of course! :LOL Just mentioning the general thing was I kept things as much the same, routine-wise as possible.
On rash issues - though I mentioned pockets, some babies do react to the fabrics, particularly the suedecloth in the Wonderoos. That's something to check out if she has any of that in her stash. Also - detergent. If using too much especially. Also - I learned here that the best treatment for most rashes is bare bottom time, that helped me.
She's going to do fine, really! Just remind her to take time for a learning curve and keep at it.
