Back to my blog's original mission: how to get your kids to sit in the jogging stroller! Dealing with children and adults alike, the most persuasive of people understand that you have to give the illusion of choice. Make them come to believe it was their idea all along. The key factor is only giving choices with outcomes that you are happy with.
Imagine! I sometimes meet some resistance from my 2-year-old when we are loading up the stroller for a run. I offer, "Spencer, do you want the big streets or little streets?" He answers, "Big streets!" Do you want to bring Goldfish or Cheerios? OK, we're off.
Now, the most likely pitfall is that your child will change his or her mind. Don't show a minute's hesitation. Be firm. No changing.
What other choices do your kids like to make for themselves?
