things to start, or change at age one

I know I can just look these things up, but I want to see what people recommend. we don't exactly get information from the Dr. mostly just "she's doing great, call or come in if you have any questions." but idk what questions to ask honestly. I want to know what you started or stopped when your baby turned 1. My daughter will be 11 months next week. we've started giving her milk (not all the time), feeding her on a better schedule and giving her a variety of foods. tried introducing sippy cups, but am having no luck with those. No negative comments please, I just want to make sure I am doing what's best for my daughter.
