I remember those shoes
. It gets easier as they get older. You just have to find that balance. It is hard to find and hard to maintain. But living a healthy life and being physically fit (because that is what weight loss is truly about) will make you a better mother, better wife and better student. It will make you an awesome roll model for your daughters. This is why you make your health and physical fitness a priority along with being a mom and a spouse and a student. Meeting your needs will allow you to meet the needs of others. Little girls especially really need to see moms who have that balance and are living healthy lives. If not they will grow up to put everybody's needs above their own. Sometimes we do that to ourselves while not wanting it for our kids!
Good luck to you! It sounds like your life overall is moving forward in a very positive direction.
