Losing weight after baby.

Afternoon guys, I am 31, married mom of an 8 month old boy. I am having a ton of trouble losing weight after having my boy. Before pregnancy I was 196#, during my entire pregnancy I only gained 18lbs... Here I am 8 months later an heavier than ever @ 243. I am looking for friends on my fitness pal who will help keep me motivated. Use map my walk? Add me there too and send me challenges! I am low carb, and getting more active by the day. My ultimate goal is 160, but for now I honestly just want to get to 199.
