Hi~
I agree that you do not want to force her to eat because it can lead to issues in the future. As far as snacking in between meals I feel it is not a good idea because you will never get a true idea of how much she is eating and as you said it gives her the idea that she can graze throughout the day. This in turn will make meal time more difficult as she will not feel hungry at regular scheduled meal times. So the idea of providing higher calorie foods is a great idea.
I work with kids with feeding issues and below I’ve listed ideas that I frequently will give to families on ways in increase calories. Keep in mind that there are “healthy” high fat foods (vs only thinking of fried foods as high calorie foods). Always keeping food allergies in mind, here are some thoughts…
* Carnation instant breakfast drinks
* dry milk added to smoothies, whole milk
* add heavy cream to foods (e.g. mash potatoes, fruit smoothie shake, scrambled eggs),
* fruit smoothies made with whole milk yogurt and fruit (fruit is high in calories)
* whole milk yogurt – can also add maple syrup to the yogurt for more calories.
*avocado
* guacamole (http://allrecipes.com/Recipe/Best-Guacamole/Detail.aspx)
* olives (great high calorie food that your child eats!)
* coconut milk in cooking (e.g. Thai foods, other foods)
* wheat germ
* Hummus (http://allrecipes.com/Recipe/Hummus-III/Detail.aspx)
* whole wheat carbs – e.g. pita, pasta, other breads
* Pesto (olive oil, basil, parmesan cheese and pine nuts purred together also see http://allrecipes.com/Recipe/Pesto-Sauce/Detail.aspx)
* Full fat cream cheese (on an egg bagel)
* different nut butters e.g. Almond, cashew, or peanut butter, nutella
* Homemade oven fries- using olive oil
* Cheese cubes (string cheese is lower in fat and calories).
* butter on all of her vegetables (and anything else you can think of: pancakes, toast, pasta, etc.)
* pour melted cheese or béchamel sauce on veggies/pasta (http://allrecipes.com/Recipe/Basic-Bechamel-Sauce/Detail....)
* Tomato-Cream Sauce for Pasta http://allrecipes.com/Recipe/Tomato-Cream-Sauce-for-Pasta...
Ideas from http://costellokids.com/therapy/calorie_boosters.html (some of the ideas above are also below. I kept them in there because it gave you an idea of number of calories per serving you can add) …
Calorie Boosters that Pack a Punch
For some children, it's important to pack every mouthful with as many calories as possible. Try adding these calorie boosters to your child's foods. Small amounts provide big calorie payoffs!
Butter/Margarine, Vegetable Oil, Mayonnaise
(35 to 4O calories/teaspoon)
Add to baby foods, vegetables, sandwiches, casseroles, soups, rice, pasta, and whatever. These calorie boosters go with almost any food
Wheat Germ
(25 calories/tablespoon)
Wheat germ can be added easily to homemade baked goodies such as pancakes, cookies, and breads. It is also good over yogurt, fruit, and cooked cereals.
Powdered Milk
(25 calories/tablespoon)
Your child won't even know when you add it to ground meat, milk shakes, mashed potatoes, cooked cereals, casseroles, and yogurt.
Sprinkle on Cheese (about 1OO calories/ounce)
Add grated cheese or cheese sauce or sprinkle parmesan on buttered toast, creamed vegetables, mashed potatoes, rice, pasta, scrambled eggs, cooked cereals, casseroles, meat, and fish.
Cream Cheese
(5O calories/tablespoon)
Cream cheese makes the start of a good dip for crackers, vegetables, and fruits. It also makes a nice spread for baked breads and buttered muffins
Cooked Egg Yolk
(about 60 calories/yolk)
Cooked egg yolk can be added to all kinds of foods. The egg yolk must be already cooked if it is going to be added to a food that will not be cooked. This is to prevent salmonella infection. The American Heart Association suggests limiting whole eggs to three a week.
Whipping Cream (Heavy)
(8O calories/tablespoon)
Add a touch to drinks or desserts.
Peanut Butter
(1OO calories/tablespoon)
Makes a great spread on some vegetables, crackers, toast, muffins, waffles-but make sure your child has the feeding skills to eat it. Peanut butter also tastes great in milk shakes, cookies, and pudding.
Sour Cream
(25 calories/tablespoon)
Tastes great on potatoes or added to casseroles and sauces.
Avocado
(75 calories per l/4 avocado)
Kids usually like avocados. Try adding them to vegetables, on top of crackers, with meats or beans, and as a guacamole dip.
Salad Dressing
(65-85 calories/tablespoon)
Salad dressings can be used on vegetables and salads and over meats as a cooking sauce. Avoid diet dressings.
Commercial Calorie Supplements (variable)
A variety of commercial high-calorie drinks and puddings are available. They come in different flavors, so try different ones to find your child's favorites. The most common types are Enrich, Ensure, Ensure Plus, and Sustacal. Some high-calorie supplements are nutritionally incomplete and should be used only as additions to your child's diet-not as the main diet.
Hope that helps - Good luck!
