I think I had dropped 30lbs in about 10 to 15 days after my daughter. I also was feeding her almost every 2 hours. As long as you are eating and drinking your water then you should be fine. I gained 40lbs the first 30lbs were easy to loose it was the last 10 that took about a year. At your check up your Dr will talk to you about the weight loss if it is something that they feel may harm you.
