Seperation anxiety?

Bella

I've been home with baby for five months. Everyone and then I would leave him with grandma for anywhere from 1-2 hours (I go to my moms regularly, like 3-4 days a week, so he knows the place and he knows her and everyone there). Last week me and SO took a trip out of town and left him with grandma and she said he cried from the minute we left. He refused to eat for probably the first five hours he was there and he cried almost that whole time. Now every time someone else holds him he begins to cry, how can I help this? I go back to work next week so he will be with grandma for 9 hours twice a week.
