It's great you're trying to stay on top of both your and your daughter's weight before there's too much of an increase. Both of you must be of small frame because the weights you describe fall into the "normal" range of weight for individuals of your heights.
It's wonderful you're doing this together - we like to remind clients that when dealing with daughters and young girls in general, it's really important not to cause stress when it comes to weight and restrictive eating because of vulnerabilities for body image distortion and eating disorders. Keep the focus on her positive qualities and insure you're spending quality time together to maintain a loving bond with each other.
What you describe for your daughter sounds really good. I would add just one small serving of protein at dinnertime, or make sure she is eating the men's portion of protein at lunchtime. When possible, choosing whole grain foods for snacks and meals (whole wheat or other types of grain pasta, rolled rather than instant oatmeal, sweet potato rather than white, multi-grain cereals and bread, whole grain foods for snacks).
You are definitely on a great start and again, what you outlined for your daughter sounds very good. Best would be have her continue to follow it and check in with her on her mood, appetite, quality of sleep, etc. and continue to check in with her therapists and other health care providers who are following her for anxiety and other conditions that someone who can physically see and talk with her is equipped to follow.
Thanks for writing in - here's to both of you feeling your best!
