Cry baby

So

Hi, so I have a 9 month old son and I’m not sure if it’s a phase or what but he cries and whines whenever I leave the room or when he doesn’t get what he wants. he is spoiled by his grandparents on both sides and we tend to spoil him as well but as parents, my bf and I have our limits and I was just wondering if anyone else is dealing with the same thing.
