Why do people....

Why do people or friends that have had a baby have the need to tell you how bad the birth is gonna be and also how hard as tiring it will be or I'll never get a minute to myself. The negitivity comes out so badly. I know it's not gonna be an easy but I'm 38 and wanted this more than anything. And never though I'd have children (not meeting the right guys or lack of boyfriends always being the single girl!) I feel so blessed I'm being given the opportunity. And I finally meet the right man to start a family with before my time ran ran out. I think to myself these people would never change having there children so why be this negitive. Drives me nuts as there's so many people longing for a baby but these people are so ungrateful. Cherish every moment with your child children.
