So today, Sydney is 10 months old and on this momentous day she started a new trick.
We were walking around (and around.... and around....) with me holding her hands and going through every room in the house when she decided to walk up to her walker. She grabbed on and started pushing it (without my help). We re-positioned it so obstacles were out of the way and she pushed it across the living room while walking behind it.
Folks... it's not going to be long now.
Later we put her in it and she went crazy. She knows how to lift the front end up over thresholds and tends to lean diagonally forward and practically run.
