Feeding

There are quite a few possibilities for your problem. She may not be getting enough variety in her diet, she may not be feeling well, she may be teething, she may just be unhappy with the presentation.
I'm lucky enough that my daughter will eat anything I give her, but she has gone through a few stages where she:
Wouldn't allow me to feed her.
Wouldn't eat anything that was mashed (she wanted to pick up her food)
Wouldn't eat if she was in her high chair.

Make sure you are giving her enough variety. Try something new or something she's always liked. Try adding something to her food for flavor. Example: Oregano, basil and veggies cooked with scrambled eggs, maybe some fresh berries in her pancakes. Try allowing her to feed herself with a utensil if you haven't already. My daughter loves the cheap colorful toss away untensils. You can also try buying the bowls with suction cups on the bottom to make the meal more interesting.
If your daughter has any teeth coming in that may be enough to curb her appetite. If you think she might be, get some teething tablets, or infant tylenol. Also monitor her fluid intake. She should still be drinking enough fluids, if she isn't and pushing them isn't helping, call her doctor.
If she continues to not eat and you can't find anyway to get food in her I would take her for a checkup. It's probably nothing serious, but better safe than sorry.

Since she's one, she's probably trying to explore her independance a little. Now she's starting to move,and communicate better and she will want to do things on her own. Try letting her fead herself. This worked for me. Put her in her highchair, give her food, don't force her to eat, but rather let her eat at her own will. Good luck.

I agree with beautiful girl, I read a great article (I'll try to find it) about how parents who feed children when they initiate it have almost 40% less likely to be obese later in life. Try feeding her when she initiates for snacks and all meals except dinner.

Be consistent and make dinner time fun, but it's never too early to learn some manners (just don't expect TOO much from a one year old). It's a good habit to into now, eating at the table all together around the same time every night. Watching you eat will help encourage her as well.

I've also heard that if you feed them one thing at a time like all eggs until they are gone, then peas, etc. they feel less overwhelmed and may eat more that way as well.

Good luck!
