Traveling Bean Part Deux

The Little Bean is a master traveler! She rode in the car for nearly ten hours today without fussing at all. She slept, played with her toys, talked to herself in her mirror, and was generally a super road trip girl. Below is a photo of her sitting on the hotel room bed getting ready to have her supper. She is such a goofy kid.

Question: The Little Bean still uses a pacifier at night to go to sleep. She ONLY uses it when she is going to sleep. I have also notice that she acts as though she might want to suck her thumb. The Gran says she is not sucking her thumb, but rather chewing on it. I don't know. I don't like that she is almost seven months old and still using a pacifier at night, but I would rather her use a pacifier than suck her thumb. Any opinions from you guys?
