I think it depends on your time management. Do you have time to wash sheets and plastic lined mattress pads every day for however long it takes her to stay dry?
I vote for night time pull ups for as long as it takes for her to stay dry all night. My grandson is 11 and still doesn't have that connection between the bladder telling him it's full and waking him up to go. He has seen a Urologist for this so we are on top of it. My 6 Yr. old grand daughter still wears a pull up and occassionally stays dry and is so happy with herself. J is 3 and wakes up often dry in his pull up.
So, my time is worth something and I choose to use my time playing, doing crafts, reading a book occassionaly, and sewing for the kids. I love doing laundry, it's my favorite chore. It usually never goes a couple of days with out being totally caught up, but I still don't want to wash peepee sheets every day.
