What do you eat for tea? Is there any reason why she can't eat what you are having?
:yeahthat:

Do you cook her a separate meal to you and DH? Do you eat together? Definitley helps our small people be encouraged to eat.
Offer small portions. Not as much as you think she should eat but a small (tiny) amount so that it looks doable to her. Encourage her positiviely and try not to let it become a battle. Any negativity associted with meal time remains for a longer time than you think and then it just becomes about the fight rather than the meal.
Try eating in a different spot for fun - have a picnic on a blanket in the lounge/outside, sit on the floor with her at her table and chairs - just somewhere that isn't associated with the regular battle.
Let her help prepare her food.
