It seems to me many actresses don't know how to act like mothers. They don't seem natural when they're around kids on screen. Sure, they try to act like mothers, since the role calls for it, but their acting feels wooden or stilted. It's not how mothers normally behave towards kids in real life.
That's a bit surprising to me because I would've thought most women including actresses would innately know how to be mothers. At the least, wouldn't they remember how their own mothers were like and try to imitate their mothers?
I wonder if this may reflect a cultural shift of some sort? Perhaps gender roles are becoming so confused in our society and culture that even women have become confused about how to act like mothers? Perhaps women are no longer having as many children so there are less children for women to be exposed to, and thus even if women know in theory how they should behave around kids, they don't know by experience how to behave around kids?
