Does anyone else have these on a regular basis?

Two nights ago, my son absolutely refused to brush his teeth before I read him his books. He insisted on brushing them *after* I read the books. But if I agreed to that, it would set a terrible precedent for bedtimes to come - so I didn't allow it. Cue WW3, aka the Battle of Wills... it was exhausting. I was tempted to give in but didn't, and so we had a massive faceoff of two extremely stubborn people.

I eventually won, but it was so painful it felt like a Pyrrhic victory. Sometimes I wonder if it's worth having these battles... I keep hoping that it will teach him that he can't just have his way, but it doesn't seem to be working.

Does anyone else have a battle of wills with your LO? Do you ever just give in, or do you battle it out?
