That's how I felt. Now I see that parents either sugarcoat everything about parenting, or are eager to relay their current source of misery: "you think it's hard now? Just you wait until they are 2/3/5/10/12/16/18!" The truth is every stage of child development has its own unique joys and challenges, with previous challenges being replaced with new ones before you even get a chance to feel a sense of relief. But, if you aren't a parent, you don't really know this, and probably ask questions that bring out the sucky parts of parenting, and remember other people's negative experiences more.
Now that I think about it, it seems difficult to really convey the full emotional experience of being a parent. Only seeing parts of it makes it easy to get an overly optimistic/pessimistic view of things.
