Do you remember the first power struggle you got into with one of your kids, and did you win?

My oldest daughter was 18 months old when I met her for the first time. She was my husband’s from his previous marriage. (I eventually adopted her.) One time I took my daughter, who was about 20 months old, to visit a friend of mine. It was the first time she and I had been alone together for any length of time.
When it came time to leave Jen decided she didn’t want to sit in her car seat. Well, I don’t know what had transpired in the past to make her think she had a choice, but as far as I was concerned, she DIDN’T have a choice. I kept putting her in, and she kept climbing back out, and slipping under the restraints and I kept putting her back in. I had no where to go, nothing else to do, and I decided we would sit there in front of my friend’s house all damn day doing this if that’s what it took. It seemed like hours, but was probably only 5 minutes, but she was getting more and more angry and frustrated. When she got to the point that she was red in the face and sweating and screaming in rage, and I was afraid I was going to do something I’d regret (not sure what, but I was getting MAD too!) I called a time out. We got out of the car and sat in my friend’s yard, where she ripped grass out by the handful, venting her anger.
After several minutes we had both calmed down. I picked her up and put her in her car seat again. She slid out. I put her back in. She slid out, I put her back in…and then she just went limp with surrender. All the fight just drained out of her. It was kind of sad, actually! But there never was a car seat issue again.
I wonder what I’d have done if I’d had to have been somewhere important, like my first day of work or had to catch a flight or something…..
