Jumping is tough, they're exuberant dogs. My female is almost 15 months, she still bounces up to kiss me and the kids (my twins are 9 and my oldest is 10 1/2). If they block her, she'll put their arm in her mouth. I've taught them to catch her feet and pinch her toes. When she bounces at me, I try to stuff something in her mouth. If I don't have anything to stuff in there, I catch her. She naturally spins to get away and ends up getting a standing up belly rub. It helps. Sorta. Beats getting muzzle punched in the face like my male did at that age!
I agree with all the other posters who said if you segregate him, it just makes him loopier. Enlist the kids and find games you can play in the house. Hide and seek is great for kids and dogs.
Your daughter's old enough to learn how to train. Girls are easier than boys at doing it exactly right and speaking in that high happy trainer voice.
5 year old boys are great ball throwers and boodah tug buddies. You might find the dog who tries to yank your arm out of the socket will let your 5 year old win at tug. My daughter makes fleece tugs for the dogs out of old blankets - cut strips 1" wide and atleast 18" long then braid them together with a knot on either end. Great stretchy fun.
Always remember a tired dog is a good dog!

I have duct tape and I am not afraid to use it.
