Elizabeth eats pretty well most of the time, though she doesn't eat breakfast at home. She usually skips it, I think because Oma (my mother-in-law, who babysits her four days a week) feeds her more interesting stuff when she gets there, and she gets to share with the dog, Belle. This causes problems on weekends or Tuesdays, when she doesn't go see Oma.
For babies old enough to eat yogurt, I liked to mix baby yogurt (the high-fat stuff is best before age two; I've just switched Elizabeth to 2%) with some baby fruit and baby cereal. It's like a really thick smoothie, and it means you can buy the big tubs of yogurt and mix it up differently every day. On the same note, toddler smoothies:
250 ml (1 cup) milk of whatever type you're using
125 ml (1/2 cup) fruit of your choice - strawberries, blueberries, peaches, bananas, whatever you've got on hand, fresh or frozen
1/2 cup yogurt (plain gives it a very sharp taste; I use vanilla or a fruit-flavoured type)
1/3 of a can of frozen orange juice concentrate
30 ml (2 tbsps) of wheat germ or baby cereal or rolled oats
A few ice cubes, unless the fruit was frozen, in which case add a bit of water.
Put it all together in a blender and mix until smooth. If you use 2% dairy products, this is a great meal for parents as well. It doesn't go very well in a sippy cup, but kids love it because it's messy and tasty. It covers three food groups and can be frozen into popsicle molds for a treat later on. Suitable for vegetarians, too.
I got this recipe from an online recipe-sharing forum, but I can't remember which one. It was breakfast practically every day last summer for the parents, and Elizabeth had the in-the-bowl version listed above. We all loved it.
