Mystified that she's not motivated by sugar

I've mentioned before Abri's stubborness. Over the past several months, she has become so picky about what she will eat. At dinner, she will often refuse the main entree and consequently eat few calories to get her by until the next meal. Our house rule says you can't get a treat without finishing what's on your plate, and we're careful about not putting too much on their plates that would be unrealistic to finish so that we don't waste food. Regardless of the rule and the no. of times we remind her about it, Abri will still refuse to eat on a regular basis.

Tonight we had family home evening and ended with a treat, and Abri did actually get one. After she had finished, she sat there in her seat for about 40 seconds, and then said in this reflective tone with a smile, "It's been a long time since I had a treat." You think? I had to laugh. I doubt it will have any affect on her pickiness, but at least I can hope.
