I don't think my DD will believe in Santa very long
After all my hard work getting my 3 yo DD to help bake muffins for Santa, then putting out a drink and reindeer food, she piped up on Xmas morning with DD right beside her and said "you enjoy those muffins and the drink dd left out?" And "you ate the carrot after throwing it on the ground?"
She also commented on the price of the gifts she got DD and how hard they were to find... SHHH MIL... I want my daughter to believe in Santa for a while longer.
