When to transition to cows milk?

My daughter will be 11 months on November 1st. Is it too soon to start the transition by giving her one bottle of cows milk per day along with her regular formula bottles? I know doctors recommend 12 months but damn. My daughter goes through 2 containers of formula a week right now.
