Hi B.. Feeding our children, I believe, can be one of the most difficult lessons as mothers. My son is 23 months old now and he goes through phases of loving to eat- to the point I feel I can't keep up, and times when I can't fix anything right. I figured out a schedule that I try my best to stick to. This has helped. Try keeping track of her bowel movement patterns. We eat breakfast at 7:45 am, little snack at 10 15isham, lunch at 12:45, I hope for a nap between 1:20 and 2:20. than snack again at 3:30, bath at 5:30, and dinner at 7:30. I know that keeping a schedule is so hard in this modern life and I admit to falling out of it (I'm working and going to school, so I can only have so much control). Though I try my best to stay with it. He is happiest when I can do this. Probably because his hunger needs are met, but even more, he has my attention when i follow this schedule.
Never pressure her into anything. I'm sure she'll eat if she's hungry enough. The reason I say feeding our children is so difficult is because I believe I can't always feed myself properly. I try to eat local organic food, and rarely eat canned or pre packaged foods because I believe in the intimacy of handling my food, but as I said, modern life makes this hard.
A really tasty and nutrient rich food is pureed potatoes, carrots, and a little bit of garlic, and sprinkles of spirulina, or brown rice, barley, and nori with a tiny bit of braggs amino acids, almond butter on sprouted breads or apples, Pureed avocado with yogurt and a hint of agave (sweetener from the agave cactus, great for diabetics).... health snack foods sometimes get's us through the day when my son won't eat meals. As she gets older you can involve her more in the process of making your meals, if you don't already. My son loves to help in the kitchen, but my goodness, be ready for a mess of fun!
I noticed he won't eat much when he misses a bowel movement. I'm still trying to figure the reason for this out. Papaya has been our hero!
Good luck, I never knew mother hood would be so immense in all of it's details, yet so simple -for the need to slow down and really embrace the world of your child is above all, the door to understanding.
