Newbie :-)

Hi there! I'm 23 years old and a mother of 2. I had our second child at the end of December, and managed to get the 30 lbs I gained off in about two months, but now I have stalled. I still have 25 pounds I would like to lose from when I was pregnant with my first child. I've been at a plateau of 145 lbs for about a month now after hitting a low of 142. I'm hoping this will give me the motivation and support that I need!
