Hi, Ellie! We are in the same boat!
I just had my first girl...my fourth child. She is already 7 weeks! My initial plan was to restart LAWL, too. Since I am nursing, I was worried about compromising my milk supply, so I am still waiting officially. I really can't seem to get my act together to get myself ready to get back, even though I want to. My baby was almost 9lbs at birth and she is probably pushing 13 or so now! I feel like I am constantly nursing. Despite this, I am stuck at about 159 myself.
I know my waters are not getting drunk and my food intake is poor also. Maybe we can stick together and support each other since our situations are similar! Congratulations with the baby!
