Because I have fond memories of endless bed-jumping sessions as a kid with my siblings we have always had an open policy on jumping on the beds - anyone can jump on any bed as long as you take your shoes off (mom and dad's bed is the only one off-limits). I've thought about putting an age cap but can't really bring myself to it.
Plus, I would hate to miss moments like this. Reminds of a quote I came across a while back:
“The laughter of girls is and ever was among the delightful sounds on the earth.” ― Dequincey
