New to MFP

Hey,
I am a 24 year old stay at home mom to a wonderful 3 year old little girl and I am looking at different workout routines that I can do with her. We will me going on walks, if the weather permits it, and I will go while she is at preschool. My goal is to get to a healthy weight so that I am healthier when my fiance and I try for our second child.

Also, I would like to invest in a fitbit but cannot see spending that much for one. Do you have any recommendations on something like a fitbit? What I want it to do is count distance I've walked/jogged, and calories burned. I would like it to sync up to a website as well.
