My son also just likes to eat bread, no congee for these few months. Then I just feed him bread with veg. and meat. Recently, I cook 烏冬, he likes to eat. You can cook the noodle with fish and 豬骨soup, it is very good taste! Try it!
My boy prefers bread than congee too.. sigh.. he ate so well b4, but now, it takes long time to feed him... doctor said may be he's just bored w the food, try to cook in a diff way and more variety, his appetite will come back later
