Oh my goodness, you will see amazing results if you stick with it and keep your eating clean!
How old is your little bub? Are you breastfeeding? If so, be careful not to cut calories to low. You may need to modify your diet somewhat to include more protein to support muscle growth.
4DS really helped me increase my weight selections and I am able to lift heavier now. I lost a couple pounds too, don't remember specifics, though.
Remember to take it easy, your body is still recovering!
