When did we get a puppy?

Lately, there have been some new behaviors around our house. No, PCH is not finally walking, but she is showing puppy-like behaviors. First off, she likes to chase the vacuum and the Swiffer sweeper around when I'm using them. She laughs and crawls as fast as possible to "catch" them. Don't worry, no vacuumed up fingers or toes.....yet! Second, whenever Hubby or I have food she comes cruising or crawling to us and stares at us until we give in and give her a bite. This behavior is very reminiscent of our beloved little doggie, Madison, may she RIP. The third behavior is perhaps the oddest or most concerning. She puts her little baby play keys in her mouth and crawls around with them, shaking them......like a puppy. If you refer to the previous post about the pee pee in the floor incident you may see why we now feel we have a puppy at times instead of a child! Who knows, if reincarnation is possible then perhaps little Madison came back to us as little PCH. Madison did die when I was very early pregnant with PCH. I don't believe in this, but I guess anything is possible! If PCH starts barking and scratching at the door we may have a problem.
