So we have been working with Buddy on sitting up independently.  He is getting better and better at it.  Today he sat by himself for several minutes before toppling over.  A couple of more days, and I think he will have it!  Took picture and video of it with my phone (since that was handy and the other cameras were not in the same room), but I have no idea how to upload it on to here.  I guess I will have to read the manual.  Yuck!
