I'm in too. I'm 7.5 months post partum, and although I got down to my pre-pregnancy weight at ~ month 4, I regained 10 lbs. Partially this is due to the holidays and everyone having delicious treats at work (and my lack of willpower), but also baby Chaskavitch doesn't sleep through the night AT ALL, and I eat more junk food when I'm groggy. Since I'm up every 45 minutes - 2.5 hours, I'm groggy all the time, basically, which means if there are carbs, they're being eaten.
I'm currently at 149, so I'd like to get down to about 135. I'm going to do my best to cut out snacking between meals, and I'm going to plan out dinners every week so we don't default to pasta with bread or buying pizza next door. Also, I'm trying to get to at least one HIIT class a week, do ~50 pushups a day, and go for a walk with baby every weekend day that it is warm enough for him - we'll say above 30 degrees F with very little wind.
My weight/squishy-ness is mostly from eating too much, but when I work out and make an effort, it is easier to say no to bad things, because I feel like I'm ruining my hard work :) Someday I'll put aside the extra money to buy myself a barbell and some bumper plates, and then I'll just do deadlifts every day, and it will be amazing.
I'll try weekly weigh-ins on Sundays.
