It sounds like you're doing great! Like my Mom said, my husband and I both use sparkpeople.com. It is absolutely free and makes it very easy to keep track of how many calories you are consuming.
I am losing 1-2 lbs EVERY week and have already dropped a pant size in just a few weeks. We went out last night and my husband bought me a cute little dress and skirt to celebrate the loss.
You can do it and it will pay off in a huge way!

Listen to your daughter about eating though! My husband was keeping his calorie count down around or below 1500 calories. His nutritionist told him to get in at least 2,000 calories a day (he is 5'10", 215) and he finds that he is more energetic and loses MORE when he eats right around 2,000 a day.
