Yup, parents may be unfair sometimes, but ultimately they love you. At least in most cases. I can't imagine why anyone who had a kid wouldn't want it. Just boggles my mind. I've been happier than I have been in years thanks to my baby. Even my girlfriend has noticed how more mature and helpful I've been. Warms my heart.
Oh I know that they love me, and I also wonder why someone wouldn't want their baby. They have made a wonderful accomplishment, bringing another person into the world. You should be proud that you have completed one of life's most important duties. Children bring love, wonder, mischief, anger, etc. But no matter what, you love them so much. Good luck!
