I exclusively nursed and pumped until my daughter was 1 year (she's 18 months now). At 10 months, during my period, she started to refuse the day-time feedings (I guess my production was down) but would nurse in the am then before bed. At 11 months, during my period, she refused all together and got frozen milk until 1 year. With the less feedings and the return of my cycle, I NEVER had engorgement (this is a tip I have for nursing mothers � if your period returns while you�re nursing, wean-when you/baby are ready-during a cycle!)
