I don't know if you are referring to girls or boys or both, but I had twin sons who are my only children, so I don't have any experience with raising girls. Mine went through that earlier than 18, and by 18 they were pretty decent young men. They are 31 now and it is true that it does get better. Mine are thoughtful, funny, kind men, and I am so proud of who they have become. I'm not sure how, but we made it and you will, too. Cherish the time you have because probably before long your 18 year old will be off on his/her own and you'll wonder how it ever happened so fast.
