I am a mom of 5, all stair steps. You are still nursing 5 times a 24 hour day. That is still too much (in many cases) to O. Cut it down to 3 times, and especially cut out the night feedings. You need at least a 6 hour period of non nursing time over night to begin ovulating. It worked for me that way. My oldest is 6 then 5, 4 almost 3 and 8 months. It was the overnight time that began my ovulation.
