Separation anxiety

It appears separation anxiety has set in for our little guy. For a couple weeks now, Trey has cried when I pick him up from school, he sees me, and then I walk away to grab his bag. Today he broke down when I left him with Daddy to go run errands, and after Mama C came over to take care of our sick guy, he cried when Daddy left the room. So far he hasn't complained when we leave him at school in the morning, but that may be just around the corner.
