C.T.
I am active duty Air Force and have been on both sides. I deployed to Iraq when my son was six months old and I've been the one to stay behind while my husband was gone. Both sides stink - I couldn't tell you which is worse.
I didn't have the hug a hero dolls to know if they would work or not. I did get the Sesame Street video about deployments for my son the last time I went. I think your four year old would benefit from it but your two year old might not grasp it yet. Children are resillient so they will get through it. You might have to deal with some acting out and behaviour that you aren't used to but for the most part they will adjust. As for yourself... make sure you have a good support system with friends around. You are going to need a break so have a friend you can trust with your kids help you get a break once in a while or you will go insane doing the single mom thing.
This is going to be difficult but you will get through it. You will learn how strong of a woman you really are when all is said and done.
Total shift of subject: I am going to message you about your schooling mentioned in your "a little about me"
