Two fun tricks I learned from visiting preschool with my kids over the years.
1. Colored Milk is fun
2. A 2 Cup measuring cup is perfect for letting small kids practice pouring. We use these at dinner all the time!
One of my kids only likes to drink crystal light or juice (which I don't let them do too often) and it always amazes me that just making milk fun makes her willing to drink it.
Plus of course it's fun to match the holidays or have a 'color day' complete with matching clothes, games and food! And the kids all love when they get to pick the color!
