Hi L.,
Welcome to the wonderful 2's. This is very common for children this age to suddenly seem to stop eating. The major reason that this is happening is.... your child is not growing as fast as she has the first 2 years. Her growth is slowing down there for her caloric needs may be decreased. This will not last for ever. Some things that you can do to decrease picky eating.
1. Stop letting her eat off of everybodies elses plates. Let her feed herself. I would put small amounts of what you are having for dinner and allow her to place nicely on a napkin if she doesn't like it. Remember what she won't eat today doesn't mean she will not try it again. The only way this can happen is to put the food infront of her.
2. Limit distactions during the meal time and sit down as a family.
3. Limit her 100% juice intake to no more than 12 oz. a day. If she is drinking more than that.....try filling the cup with ice. It takes up space but still saves you an agument.
4. Limit her 1% milk intake to no more than 20 oz. a day. Milk will fill up a child and cause picky eating and sometimes low iron. Every thing in moderation.
5. Never have any forbidden foods. Everything is there to enjoy. Just remember the words moderation. Once or twice a week is considered moderation.
6. Offer (place in front of him) food 3 meals a day and 2-3 healthy snacks. This will allow her to eat more often and smaller servings.
7. Keep in mind that his serving sizes are about two tablespoons. So, sometimes they are eating as much as they need but not as much as we would like them to eat.
8. Offer water only 1 hour before meals/snacks and after meals and snacks. This way he won't be picking at the food, not really hungry. You may even wait until he is done eating before allowing her to drink.
Last but not least..... Your job as a parent is to offer the food. Her job is to play and have fun. Also, she is to decide if he would like to eat, how much would he like to eat, or if she is going to eat. You are doing your job by offering the food. As long as he gets something that is somewhat healthy and we offer her what we are eating, you are doing a great job!!!!
