Well, actually all babies are cute, but Asian babies lack the large eyes as feature of the biological cuteness scheme, which white and black babies have. (You know, these features like "Feed me"-mouth, high and round forehead, little nose, large eyes)
Apart from that Asians traditionally tend to overfeed their newborns to have "lucky babies", which can look strange at times. When I was a baby, they fed me so much smashed banana and milk that I was sooo fat that I looked rather deformed and like a miniature Sumo fighter in diapers. It really gives me the creeps when I take a look at my baby pictures. And that's not a bad case of racial self-hatred, but one of being realistic. hehe.
Yet as soon as they're a little thinner and a little older, they're just as cute as any other child.
