New here as well and in the same boat!
I was 190 before getting pregnant, ended up being 232 the day I gave birth. My son is now 6 months old, and I am stuck at 216. I was breastfeeding at first and lost 30 pounds within days of having him... However, my milk supply never fully came in and I've since switched to strictly formula..and packed on the 17 pounds bringing me to an aggrivating 216! I walk an average of 3 miles every 2 days but just cant seem to lose anymore. My eating habits were HORRIBLE up until about a month ago, which surprises me that I haven't dropped anymore weight. I wouldn't say I have eat great now, but I definately make healthier choices! I literally had fast food at least once a day until a month ago. Now, I get Subway maybe once a week, sometimes we order Piza once a week, but I don't eat the portions I used to either.
Before I got pregnant, I was an athlete for years and had always flucuated with my weight, but never had a problem dropping whatever I needed to within a months time. This is VERY hard for me to adjust to and it seems no matter what route I take, I'm stuck where I'm at! My husband comes home from Iraq in October so I NEED to lose 40 pounds before his return!! HELP PLEASE!
