I made a turkey sandwich for DD4 the other day, the one food she seems to eat consistently. Knowing her tendencies, I made it as perfectly as I could, but after I cut it in half I noticed one side didn't look quite as good as the other. Still, both halves were definitely the same sandwich.

I brought it to her on a plate and she took one glance, pointed at the "bad' side, and scream-cried about how she doesn't like "that kind of sandwich." She then took a second look at the other half and gobbled it up.

All that to say, we haven't really figured it out. We often use the dessert ransom technique which works about 75% of time. DD tends to eat a lot of cold food.

Our SENG discussion group leader said that was one fight she never picked since there were so many others, and her children managed to stay healthy. They would finally would eat big meals when they got hungry enough.
