My 5 year old son is really kind, smart, he's an excellent communicator, and he's even tough when it comes to bumps and bruises. Overall he's a great kid. However, he really struggles with making concessions. He consistently throws a fit when he doesn't get his way or things don't go as he planned.
For example, yesterday we had "game time" and his younger sibling asked if we could play a matching game, then my 5 year old is immediately in tears crying that he doesn't want to play that game before I've even had a chance to respond. This type of scenario plays out over and over again. There are many cases where he could just talk to us or his sibling but he just gets set off so easily. He's sort of a control freak but a 5 year old can only have so much control and this just sets him off throughout the day, everyday.
He was in preschool but we took him out when covid hit. We are sending him back soon and he starts kindergarten in the fall. I'm a little concerned that this behavior will ostracize him or make it more challenging for him to make friends.
What can I do to help him be more adaptable and resilient? How can I help him control his emotions so that his default isn't an emotional outburst?
