It's so funny how different my kids act when they are separate than they do together. When I only have one of them around then they are quiet and listen so much better. They are sweet and adorable and loving. Jason will play with blocks or color pictures and make up stories. He says the funniest things and gives more hugs and kisses. Jakey will be cuddly and sweet and content to lay down quietly with me.
Then you put them both together and their energy multiplies 100x. They are bouncing off the walls, making messes left and right, disobeying, and just generally driving me crazy. I really don't know how it works, but they transform from angels to monsters when you combine them. And I know it's not just my kids. When I've been on playdates or gone to someone else's home with small kids, they all group together and go insane. Not that they always act "bad", just they suddenly have much more energy than a category 4 hurricane whenever you have 2 or more children in the same room.
Just watching children play together makes me exhausted. If only I could have that much energy all the time, I would be able to get so much more done lol.
