There is a limited period of time where you (the parents) will be the sun rising and setting for your child. (A few years.) That was special for me; there's no love like the love of a young child.
After that, your kids will start to turn towards friends, teachers, and other relatives. As they should--it's an important part of becoming a full fledged human.
But it's still a bit bittersweet to see the end of being able to do no wrong in your kiddo's eyes.
