In the past, DD1 used to take 1hr to finish her food. It was rather exasperating. I decided to implement a "Reward System". Whenever she finishes her food within 30min or less, I will give her a sticker on her chart(which comprises of good attitude towards doing homework, practising piano, taking care of her baby sister, clearing up her room, behaving herself). If she doesnt, she will be given a sad face. Upon getting 60 stickers, she will get a treat like extended TV/game time for a day. 100 stickers will earn her a movie or an excursion.

In preparation of her food, I would cook her most hated food with her favourite food to lessen her pain in eating. For example, I chop 'yukky spinach' into teeny weeny pieces, dump it into her favourite kombu and anchovy stock. When the soup is about to boil, I stir in her favourite egg together with some cornflour to make it a little sticky(aka her favourite-restaurant style). In this way, she slurps down her spinach smilingly.
