Things other than cuteness are at work when people decide what to take videos of. Possible considerations here:
1) Babies live in people’s houses. Fewer bunnies do.
2) People are interested in babies as relatives, conspecifics, and insight into child psychology.
3) Babies—past a certain very young age, anyway—have a wider range of behavior than bunnies.
4) People like to document the lives of their children for future reference.
