I'm happy to say that I hold no grudge against someone who only has ooey gooey feelings for their kid's sleepless nights and cannot get enough of their messy diapers.
However, sadly, many of the posters here demonstrate their intolerance and unsympathetic nature with their vitriol for anyone who simply finds parenting a difficult job. I would never claim that being a parent does not come with gratifying moments but how is it that you cannot conceive that some people may be having a harder time than you or did not receive the same amount of preparation for this role?
Instead of putting yourself in my shoes you are rallying around your children in a defensive posture unwilling to see the difficulties that others might be having.
Speaking for myself, it does seem as though you've been incredulous about others' claims of happiness in child-rearing, and that's mostly what drew my responses. But I'll take you for your word for it if you say you understand the other side of the coin.
On the other hand, I don't think it's crazy for a person to feel overwhelmed, or not enjoy the experience of child-rearing. But don't say woe is me, work toward a better experience. I'm not a professional, so I don't know the what's and how's of improving the experience.
I do however think it's important to reiterate george's point above, that it's crucial that you don't show this attitude to your children, because it can be very damaging to one of the most important relationships a person ever has.
