It's quite comforting to see how many people say that they are glad (and happy or blessed) that they're a parent! Looks like 90% or so, if one were to score these responses. No need, it's all clear and interesting to read and understand how so many of the accidental parents learned to love the babies and were glad that they kept their kids and/or didn't run away from their responsibilities.
Thanks NoSoup for your original post, and everyone who has shared their story since it gives me some hope for our future. Those of you who are "absolutely opposed" must have your own private reasons for being so down on having kids.
It's no surprise that loved kids tend to become loved parents.
