I was religious about timing-15 mins on each side, switching sides each time, etc. Now, I just feed every two hours during the day and at night whenever he wakes up. Night is killing me because I selfishly want the sleep but I get sooo engorged I just put him on whatever boob hurts more. Afraid this will come back to bite me...I'll nurse him on one and switch him over after a short period of time, but one day if he refuses a boob because he's full-it will kill me!
