My son will turn 1 in two weeks.  He still gets 4 formula bottles a day (6, 11, 5, bedtime).  It's only 22 ounces total, but I'm thinking I need to start eliminating formula soon.  What is the best transition to whole milk?  When do you all give milk (at meals, just at wake up or bedtime)? Should I completely take bottles away when I introduce milk? And last question.... Do you warm the milk?  He really likes his formula warmed.
