We have a big bonus room upstairs in our house that we don't know what to do with yet, so right now it pretty much just consists of a mattress on the floor. One of Grayson and Emma Claire's favorite things to do every day is to jump and roll on the mattress. I love it because it helps get some of that never-ending toddler energy out and they fall asleep much more quickly at night. :) Last Friday Grayson's friend, Hayes, came over to play and they had so much fun running and jumping onto the mattress. So cute!
