Thank you for bringing this up. I get so annoyed when a celebrity's baby bump or their little kid's new look is the top story. have they nothing else to report on?
I believe our culture has shifted somehow and now baby bumps considered to be fashionable or status symbols. look at what is on TV... teen mom, the duggars, kate plus 8. That is sending a really bad message to young girls. (as is the show sister-wives, but that is besides the point)
As a culture we spend way too much time focusing on stuff that only makes us stupider. If we have to talk about celebrities how, about we talk about how Natalie Portman went to Harvard not Beyonce's baby bump.
There is really more to life than just having kids. Really, there is. And if you believe that having babies is the end-all, be-all of life, than you aren't really living.
