A tooth?!?!

Could it be true? We are thinking Riley has her first tooth!! We would have no idea if I had not stuck my finger in to check the "progress". She has not been cranky and has given us no signal that something was growing. Maybe that is because she is too busy moving EVERYWHERE!! If Riley is not crawling somewhere, she is pulling herself up on something, or following Buster around. Her new favorite pass time is to crawl after him.....everywhere he goes. He is such a good puppy that he just lets her and doesn't care. She will crawl over him, on him, pull on his legs, use his legs to try to stand. He is very good and just loves her to bits. I have a video of Riley standing up in her crib that I will post later. We are having trouble getting her to sleep for naps and bed now because she just wants to stand and play. But once she stands she can't sit back down without falling back down on the mattress and that scares her. We also just went a bought a HUGE baby gate that can actually be made into a play pen too. But we currently have it around the TV and TV stand, and the Christmas tree. She LOVES going to the TV stand and trying to stand up or push buttons. Hopefully it helps!! Pictures and videos to come later!
