Actually.. other things can double as one :)
You know.. to be honest, we NEVER use our changing table.. ha! We use either our bed or the floor! It works so much easier for us.. I like changing him "head on" instead of "sideways".. it just seems more natural to me.. and now, I don't like any other way :) Who says you need a changing table.. I DON'T :)
But, I still use the bed and floor as well.
