Yes. You're going to need to avoid all dairy products. This means butter, cheese, sour cream, yogurt, cream cheese, etc. It's hard at first. I think the hardest part for me was finding a milk substitute. I found I liked chocolate almond milk, but I can't drink it because of her nut allergy.
I learned a lot from godairyfree.org. If I had questions when we were out and about a quick google search for the specifics sometimes helped. I wish you good luck!

Have your pedi or allergist give the the list for alternative names for dairy that way when you're looking at ingredients you can spot the hidden diary.
