I took my first trip (7 days) away from my 2 year old baby girl! We talked on the phone most nights and she was always so happy to talk to me. I was completely surprised when I walked in the door and she started crying and running to daddy. She didn't want to have anything to do with me. Every time I would try and look at her or talk to her she would scream at me and try and hit me. I thought she would run to me, like she does when I come home from the grocery store. What is going on?
