A dash of cinnamon helps the milk go down
Here's how Whitney (one of the Rookie Moms) makes milk more palatable for her non-milk-drinking daughter:
My 14-month old daughter does not like to drink milk. My pediatrician suggested offering chocolate milk and then to slowly reduce the amount of chocolate I add. Somehow, I just can't get comfortable giving my baby chocolate milk. (Plus then I have to keep it in the house and constantly negotiate about it with my preschooler.)
Recently I was making my almost-4-year old a special drink of foamed milk with a drop of vanilla extract and a shake of cinnamon in it, when it occurred to me to offer this to the baby as well. She drank some! Over the next few weeks I dropped the vanilla and simplified it to a shake of cinnamon in the cup before I pour in her milk. She's drinking more and more of it. No guarantees on toddler tastes of course, but warm cinnamon milk seems pretty hard to resist.
Also delicious: a pinch of cardamom.
