We have this dvd and I have a warning about it. First of all, it has comments from "real" soldiers in it (real meaning not puppets) and I watched this about a month after DH left and it was very emotional for me. Also it was confusing for my DS because DH was gone, but they also showed the homecoming on the dvd and he didn't understand that time had passed so this really didn't make sense to him since his Daddy had left, but hadn't come home yet. He had just turned 3 when he watched it, I think it might be more suitable for a child that's a little bit older and has a little better concept of time.
That's just my opinion, of course, someone else may have had a better experience with it.
