As a new mom myself, I understand how difficult it can be to lose the baby weight. A few suggestions for you:
You didn't mention exercise - For weight loss aim to get 5 days of mod. intensity activity of a combination of cardio and weight training.
Watch the BLTs, which stands for Bites, Licks, and Tastes. It's so easy to take a few spoonfuls of our kids food here, a little bit there and it all adds up. Keep a food diary so you know exactly how much you are eating.
