Some people have all the luck!
My daughter fed magnificently from birth, despite a forceps delivery, but
slept throught the night from 4 weeks (she made up for it later!).  The
result? Menses returned at 7 weeks.
My son had difficulty latching on (no forceps) but fed around the clock.
Result? Menses returned at 10 weeks.
NOT FAIR!
