((Wendy)) - I'm so glad to hear your son made it back safely - and has good love in his life to keep him strong.
My friend's son-in-law went on his first tour when his daughter was 1 y.o. She was a daddy's girl all the way. When he returned, she didn't recognize him - broke his heart. It took a while for her to become close with him again - just in time for him to return for another tour in Iraq. He's over there now.
