Having just read the pending pile thread, I wondered how many times your LOs wear their pjs before they are "dirty"?
DTs are grubby little mites and crawl around so their sleepsuits/pjs get worn just once, but dd who is 4 is much cleaner and less of a floor-roller so she wears her 2, sometimes 3 nights before they are dirty/a bit stinky.
Is this a slatternly way to live? Should they have clean pjs every night? Surely not...
