Please SOMEONE help!

So, I’m not sure what to do. I’m a first time mother, and a new army wife. I found out I was pregnant when my husband was just getting into the army life before we moved to our first duty station. I live 7 hours away so my son ( who is now 2 months ) barely got to meet them. I recently have been home to my parents house now for a week without my husband since he had to work. My son cries when anyone else but me holds him. I don’t know what to do about it or if something is wrong. Has anyone else experienced this ?
