I like babies and small children in controllable doses. Most people's babies are ugly or weird looking, but I am overcome with a potent case of the "d'awwwws" when I see a really cute infant or toddler! My three year old little sister, for example, is absolutely precious, and I enjoy her presence when she's not being a brat. She has this most adorable heart melting voice and smile!
So it really just depends. In most cases, no. But if the baby is particularly cute, or fascinates me in some way (e.g., shows signs of high intelligence), then yes.
