It is best to admit defeat and use it to your benefit rather than continue fighting a lost cause based solely on principle. Case in point -- the princess phase. I have fought it kicking and screaming, but DNA, preschool friends, and commercialism has won out. And, because it is literally almost all that she can think and talk about, getting a bonafide brand new Rapunzel dress is something Maeve, apparently, cannot live without. So, I am willing to sell my soul and buy the dress to avoid thousands in orthodontic bills later in life.... And, Maeve is 100% on board with this plan. She asks to have the icky stuff put on her nails and looks at the picture of the dress she is about to inherit several times a day.... The night went no problem too... so, that's a major bonus. She is so proud of herself. I think we have a winning situation here. Yay!
