Naughty, naughty.  This is in the archives.  Maybe in Australia where
almost everyone breastfeeds, it seems that breastfeeding causes
postpartum hair loss. The truth is that *all* mothers, breastfeeding
or not, lose hair after the birth of the baby, typically around 3 to 6
months postpartum.  Some lose only a little, others have dramatic
loss; usually most grows back.
