Around our house we have no problem getting anyone to drink milk. We go through about 7 gallons a week when all of the kids are home.
One day we found banana milk at the Grocery store and my kids love anything banana, so we tried it. They of course loved it. For a half gallon it was about $2.40. I thought there has to be a way to make this. I found banana extract in our grocery store that I picked up and just added about a 1/2 teaspoon of sugar to a small cup of milk. They love it. I know artificial flavor and sugar, but come on they get 3 times the junk in just a piece of candy.
We have tried lots of flavors. We made strawberry syrup from the strawberry jam that I made last summer. Also, if you have Nesquick you can add that instead of the sugar in the banana milk. 
The stores have all sorts of extracts in the store. If you are concerned about chemicals you can try to find natural extracts or make you own. Just have fun. Milk is a plain base that goes well with most flavors. Hey, I just thought of Peach milk, you know peaches and cream. I might have to find some peach preserves and melt it on the stove and add a little water. Yum!! Have fun!!
