Watch little brother's ecstatic reaction when he learns his mom is pregnant

Faith Christopher and her husband revealed her pregnancy to all three of their sons at the same time, but it was clear the youngest was the most excited about the news.

Christopher, a fitness coach in Tampa, Fla., wrote on Facebook that she "freaked out a little bit" when she found out she was pregnant with baby number four. She and her husband wanted to tell their kids in a special way, she said, "because they've been asking for a little brother or sister for a long time."

So the Christophers sat their kids down on a Sunday night and told them they had a "super special cake." The boys realized there was something written on the cookie cake and wondered what it might be. Max -- the middle son -- guessed chores.

When dad sat the cake down, the eldest son exclaimed, "You're pregnant?"

Andrew, the youngest, jumped from his seat, screaming "Yes!" repeatedly and even rolling on the floor before explaining his true cause for enthusiasm: "I'm finally not going to be the younger one!"

Max was not so enthused.

"I can't take this. I'm going upstairs to cry," he said.

When she posted the video, Christopher assured viewers, "I swear my middle son is way better now."
