A pacifier and a thumb!
The other night while Tony was holding Ruthie trying to get her to sleep, she had her pacifier in her mouth. This is the kind they give you at the hospital (Soothie brand) and the nipple is hollow. Ruthie had managed to get her thumb perfectly inside the nipple of the pacifier and had her fingers wrapped around her nose just like she was sucking her thumb...except for it was inside the nipple of the pacifier.
It was quite funny! What a girl!
