3 year old very possessive

They both started at the same time. They have never been apart.

I had a little guy that came with his brother. When his older brother was in school everything went smoothly but after we picked him up, not so much. The parents, grandparents and older brother were very overprotective of this little guy. As a matter of fact the parents and grandparents were also overprotective of the older boy as well. Could this be the same situation?
