losing my mind!!!!!

Rubi
Has anyone's baby been extra clingy or crying so much more than usual lately?? My boy is 7 months and all he wants is to be carried now. I didn't carry him much before but now he cries where ever I put him and just wants me to hold him. He's been crying so much at night when he used to sleep through the night. What could it be!!!!! Any suggestions on what to do or what helped to soothe your little one? His cries are almost as if he was in pain, but as soon as I pick him up he stops. If you have any tips I would appreciate it!
