My "niece," Lilit, was born one day after Cai. He's been visiting her since she was an infant and he was a puppy. At first he didn't care about her at all - sniffed, then ignored. He wasn't bothered by the sounds of baby crying or laughing or shrieking. As she began to walk and reach out and touch, he became just a little nervous about her. (Many dogs dislike toddlers because of their unpredictable movements and noises, and grabby-ness.) Treats and careful supervision are steadily bringing him around. The last visit was particularly sweet - he sat on his Auntie Miki's lap, and gave Lilit sniffs, kisses, and tail wags.
