How old is your baby now? I could have almost written this (just sub nursing school with living with my MIL and trying to buy a house!). I gained 60lbs during my pregnancy and only lost 20 after the birth. I was not getting in hardly any Water, eating whatever I wanted, and had basically forgotten what it was like to ever be a good bandster. My baby will be 13 months tomorrow and It wasn't until my last fill (under fluoro) that I have finally started to feel in the green. As bad as it sounds, it really took being in the green to motivate me to follow the rules better (not to a T, but close!). I am back on My Fitness Pal (add me if you want! erinistehawesome), trying to get my water in, and keeping my portions down. Granted, now that I'm in the green, I don't have a choice and I feel miserable if I eat more than a cup of food. Of course, there are days (like today) when I am constantly wanting to eat (stupid period!) so I will eat a little something, wait an hour 2, eat more, etc. It's bad, but I'm trying to keep it healthy. Celery and PB, carrots, apple, swiss roll (oops!). You don't need to jump in head first, just change a few things at a time.
Also keep in mind, is not going to go super fast! It took me 18 months to loose 97 lbs. Slow and steady and consistency! Please add me on here and everywhere else and we can be 'just a baby' buddies!
