So we finally went out and bought Alexander and "exersaucer-type" thing... It's actually called "Baby Einstein" made by Graco. I believe Evenflo has the patent on the name "Exersaucer" but it serves the same purpose. Alexander was in need of of some entertaining...some stimulation...and we needed to give him something else to do besides watch NOGGIN all day.
Here's a brief video of him playing with it for the first time. It was too cute. I anticipate much use out of it and more mobility once his feet can firmly reach the bottom... ;) (Midnight apparently wanted some camera time and can be seen lurking in the shot.)
