I really think Tucker is going to walk soon.  He doesn't even like being in his walker as much because he is always crawling around the house and pulling himself up on things.  He doesn't even need the couch or a table.  He'll use the wall to lean against.  He'd rather be standing up than doing anything else.  I've had to make some adjustments in my house.  He did get into a candle that was burning (oops, but no injuries) and nothing that is breakable is within his reach.  It actually worked out good for me because I don't have nearly as much stuff to dust anymore.
