A Growing Playpen

I can really appreciate children’s furniture that grows with the child.  It seems like we have left a string of outgrown furniture behind us with each of ours.  Now I have found a playpen that recognizes the fact that children grow.  When you buy it,  you buy it in sections.  It is easy to start with a simple square and then as the child needs more room or is a second child is added another section or two can be added to the mix.  I would guess the possibilities are limitless if you have the room to keep adding onto it.
