do spiders move there babies if in harms way?

Answer 1

Generally, no - some spiders guard and defend their eggsacs and even very young babies, and some (notably wolf spiders) carry their young on their backs for a time after hatching), but other than that last, I know of no spiders that relocate their eggsacs or kids if the situation changes after laying/hatching.

Answer 2

I'd say rarely if at all.
