My 9-month-old has been sleeping through the night (12 hours) since about 4 months, with a dream feed around 10 pm until maybe 7 months. A week ago he started waking when we go to bed, and again around 3 or 4 am, wanting a feed each time. Almost right away, I got my period, even though I'd gotten it a week earlier (my periods are only about 3 days since they came back, it's definitely another cycle). Has anyone experienced anything like this? Is my weird menstrual cycle related to the renewed nighttime feeding?
