Hey girl! Congratulations on your new bundle of joy!
My first comment is to not be hard on yourself for the weight -- your body just went through 9 months of stress plus one big catastrophic event so it may be askign for some time to recover, esp after the additional trauma of a c-section. I've never had a baby and I can't say that for a scientific fact, but I don't think its impossible that you need to give yourself some leaway because of what you're asking your body to do, on top of the stress of just taking care of the little joy ball.
Can you start by reading the sticky at the top called "Are you new to EF Ladies Board - START HERE" -- there's a short list of detail that you've given some of , but especially the specific daily meal plan and the food counts detail that you can get out of a food counts program like
www.fitday.com (its a free account online - takes a few minutes to set up your food definitions, but it is very easy to use and very useful!) so that we can know for sure just how much you are eating and what exactly you are eating.
Diet is usually the one place to start to look at to achieve your goals. Weight, btw, is only a measure of the total mass of your body's muscle, skeleton & fat. So its almost irrelevant when you are talking about "losing weight" -- you really want to decrease your bodyfat and/or increase your muscle.
Just eyeballing your diet, I think you are way under-eating, especially for the energy you need to keep up with Junior. Your body is thinking it's in a famine-mode where there simply isn't enough food around, so it has adjusted its metabolism down a bit to preserve the energy sources it has (bodyfat). And thus, you aren't burnign fat efficiently. I'll also add that generally I recommend eating as much REAL food as possible. The protein bar probably isn't killing you, but there are better sources of less-processed food available. I also see very litte fats in your diet and very little carb. Do you feel tired or flaky all the time? (Symptom of too little carbs.)
And finally you should get your bodyfat measured so we can talk about how much of you is muscle and how much is truly fat. Using the scale to judge your progress is just not the way to go. In the first part of my prep for a bodybuildign show, I lost 8% bodyfat but the scale didnt' budge more than 2 lb from 160 lbs for 3 months of intense dieting, cardio & training.
