Anyone in their early 20s who recently had a baby?

I have an almost 7 month old daughter and I absolutely love her, she changed my life in all the right ways! But she gave me some REALLY bad cravings (aka pizza! haha) and I ended up gaining 55 pounds. I have lost 50 of those pounds so far, but I'm still 12 pounds away from the weight I was when I first met my amazing fiance I would eventually like to get down to 155!
Anyone else recently have a baby who's trying to lose weight? I'm 22. I could use some new friends my age to motivate eachother!
