I was being nosy and noticed that you are breast feeding. I also breast fed my son till he was 6 months. I did not start dropping the weight till after I dried up, which made no sense because your body burns more calories when you are producing milk. I would just be patient till you wean then start cutting calories and vary your workout everyday. I did that and I was dropping 5 lbs. every week. I did 1/2 hour yoga, 1/2 hour aerobics and walked 2 miles everyday. I worked different parts of my body each day. Your muscles need variety. Don't be so judgmental! You have 3 kids and you are under 130 lbs. Hope this helps.
