Read above post first.
As your child is approaching the teens, your relationship grows and life becomes more fun and easier. They are not a baby but still your baby. The teen years are the best. You no longer need a babysitter, you can actually talk to this child and reason with them (more or less) and they understand (even if they deny it).
Raising a child is so rewarding. Reflect back and think of all the things your child does, what they learned and how they have matured to this point in their life. How proud are you? Now look ahead and think of the things yet to come: finishing middle school, going to high school, proms, driving, first date etc. How proud do you think you will be then?
Knowing that you raised this young person to be the person that they have become should give you the warm-fuzzies.
