Hi

I'm trying to remember a film scene of a woman who is climbing up either the inside of a wall or inside the attic to spy on her kids in their bedroom. When her kids see her through a hole in the wall they all start screaming before a little girl says ''look, its mom'', she says ''hi guys'' before she ends up falling out from wherever she is and bounces on a trampoline. I'm sorry this is all I can remember. If anyone knows what it is, what is the name of the movie?
