We just tied a ribbon arond sophie, an oball, teethers, etc. Sometimes I clip the loop on DS' Hello-a-phone (http://www.amazon.com/B-Hellophone-R...1429614&sr=8-3) to his straps.
"Someday, I am going to go to bed without toys on the floor and sippys in my sink. Things will stay where I put them and I can have nice, fragile items on display. But when I do, I will look around with a wistfullness in my heart and miss the days where vibrant imaginations ran wild and there was evidence of life happening around me all the time!"
