There's something for people like you under 'forums' . :)
Sounds like your doing a lot and lost 20 lbs that's great!!! Be patient with yourself its not an overnight thing. Did you work out while you were preggo? Did you pig out on unhealthy foods? Did you have gestational diabetes? All these things matter when trying to lose baby weight it takes about 2 years for your body to get to a good size after baby. But with all you're doing your ahead of the game. Also breastfeeding helps.
