I’m not a mother, nor do I ever plan on becoming one, but now that I’ve been out of the virtual hell known as adolescence for awhile, I can say that, while your child may not always like the choices you make for her, she’ll understand them better when she gets older.
She’ll also realize that you don’t know everything – even if you claim differently – so stay on the up-and-up about that. Being stubborn won’t get you anywhere. Being understanding will.
Good luck with your new baby! I hope you get to meet her soon!
