My DD (15 months now) was on grown up food early, by about 10 months I would say. She is actually a fantastic eater compared to other babies I know. I make sure she has a protein, car, and fruit or veggie with each meal, although with breakfast there is usually no protein. I will list the things she eats: Breakfast
Dry cereal with fruit (pears, peaches, fruit cocktail, banana),
Cereal bar with fruit, or
Waffle with sugar free grape jam
scrambled eggs with a little cheese Lunch
Lunch meat ham or turkey (she will only eat cubes, not slices) with fruit and crackers or a slice of bread with jam or tator tots
Grilled cheese sandwhich with fruit
Macaroni and cheese Dinner
Whatever we eat. She likes chicken, seasoned hamburger meat, peas, brocolli, carrots (canned because they are nice and soft), any type of potato (mashed, baked, boiled), rice, sweet potatoes, sweet corn, soft tacos, pot roast, spagetti
For snacks we do juice with ritz crackers, cheez-its, bananas, cereal bars, Gerber cookies, dried cereal.
She is such a star at eating that she already uses a fork perfectly! And that started a month or two ago!
It is totally normal for food to go on the floor. It's not because they don't like it, it is because they just want to watch it fall to the ground. Grace doesn't do it so much anymore, so it will pass.
