Heather: So glad you have discovered SparkPeople and am excited about the many Spark Friends you will make who want to help you in any way they can.
Do you try to teach your girls how to play ball. I think that would be great for all of you. Are there any other things you enjoy doing? The reason I'm asking all these kookie questions is because you say you are bored. That can lead to some unhealthy habits--as I'm sure you have discovered. (Like snacking on sugary treats to get some energy--this is my weakness).
A friend of mine enjoys helping with the reading group at the local library. It gives the kids a leg up when they start school. Or a ball team for youngsters?
Make a list of the things you enjoy doing and go from there. Both you and your daughters will benefit.
Best of luck, make some SP friends, and define your goals, sweetie.
