These cups,bowls and plates from Ikea are something I have bought for years - for my own kids as well as for baby gifts. I love the bright colors and the price is right too. $1.99 for a set of 6 cups, bowls, or plates.
I have recently started adding the cups to my Operation Christmas Child Shoe boxes. At .33 cents a piece, they're perfect.
Another idea would be to include some of this flatware. An 18 piece set is $1.99. That makes a set of one fork, knife and spoon .33 cents.
One of the great things about these items is that they would suit either gender and every age category. Perfect!
