Mukta - that's what I do, have a little something to eat with the boys at their dinner time, then I have my proper meal with DH once they're in bed at about 8pm. I definitely think it helps for you to be sitting down concerned about your own food rather than have them feeling you're watching, much better for them to think you don't care how much they do or don't eat! Your food sounds yummy btw - can I come to dinner? I promise to eat it all up! Just another thought, could you find a way to improve the taste of the steamed veggies, some type of sauce or something? I don't like plain steamed veggies myself and the boys wouldn't touch them either but if they're made more interesting some how..
