Hi Catherine,
I used them and still use the trifolds, i usually stuff them into a pocket or will use them as they are intended with a BBH cover.
I have a friend that used them exclusivly with twins and then another baby, at one time she had all three in nappies and swore by them.
TBH i prefer BBH now to them as they are more absorbent, but in the early days they are brilliant

HTH
