so I don't know if I am over reacting or what but my fiance wants to do Christmas and our babygirls first birthday together and I told him that I didn't want to do it that way because it's her big first. I know it's a long ways away but I like to plan and start buying stuff early and not all at once. it just makes me upset. what are your thoughts?
