Too many monkeys jumping in the bed

Recently, we have been putting all the guys down for bed around the same time ~ 7:00p, so we will read to all of them at the same time. They are way too mobile to sit in our laps or lay on the floor to read books so we put Parker and Jack into Jack's bed and read them their books. They get so excited at certain parts of each book and they giggle and jump up and down while holding onto the railing. Owen wants to get in on the fun so we will put him in there too and he laughs just as much jumping around. We have only had a few slight knocks of chins and heads, but it is really cute especially when they lay down and crawl all over each other. I know we should probably start splitting them up before someone gets hurt but they seem to have so much fun before they go down for the night.
