How adorable! And by the way, I know how your DD feels. My first (now 30) was an absolute angel too, sleeping through the night almost from the day I brought him home and then my DD (now 29) was born and she was the exact opposite. She never slept for more than 2 hours at a time for the first 6 months! Turned out she was allergic to cow's milk and traces of it were getting into my milk and it took them that long to figure it out. Put her on soy milk and the change was immediate. She slept through the night the very first night and it was like I traded her in for a model that worked! LOL Enjoy your grandbaby as they grow up way too fast.
