Hi mamamccain11!
Calorie counting is a great way to lose weight and there are a lot of people on the forum who know their stuff, so ask lots of questions if you need to!
I have one question for you. Are you still breastfeeding your 8 month old? If you are you should raise your calorie level since breastfeeding burns lots of calories. If you aren't then your calorie range sounds reasonable. Most people will need to lower their calories as they get closer to goal, but it's recommended that you don't go below 1200 calories in a day. So when you get closer to goal it may come off a bit slower (this is normal.) Exercise and patience help a lot!
You'll do great!
