is she cutting her 1 year molars???
do you talk to her about where her daddy went?
my husband is military and is gone a lot. when my girls were younger they went through all sorts of weirdness when he was gone. what seemed to help them was talking about where daddy went, and what daddy was doing and such. and i'd let them talk to him on the phone every time he called. he's deployed now and my girls get to talk to him on the computer camera and i know that helps them a lot!
anyway, hope it gets better for ya'll!
