Why all the negativity??

Rayyy • Due end of April!
This is not a rant about you guys by any means. I'm just so tired of so many articles online and on Facebook. 
This morning someone tagged me in an article to the effect of "9 things I wish I knew when I was pregnant the first time". 
This lady went on and on to rant and rave about how when you are "pregnant but not a mom yet" you have no idea what you are talking about. You think you are tired - well I'll give you tired. 
It just makes me mad- and sad. I'm so excited about our little boy but reading all this seems so discouraging. I KNOW it will be hard. I know I won't be living the same way I did before I was pregnant or had a child. I know. But how come I never see any positive articles about having kids???
