K.K.
I agree with a previous responder about nutrition absorbtion. She may not be getting enough. Regular MDs wont' tell you that. You will get better advice from a Naturopath or an Integrative MD (is an MD but understands and uses a wholistic approach) Has she been checked for food allergies or sensitivity? If she's got some intolerances, then she's not going to get the nutrients absorbed well. Calories themselves mean little unless they are nurtient dense. A salad doesn't have many calories, but is very rich in nutrients. Is she eating greens?
Just another bit that might help you: Have you tried whole food juices (fresh and raw, not store bought pasturized) or smoothies? My kids LOVE these, and they get greens in there too, without the "yucky" taste! Here's some ideas if you'd like to try them:
Kale Kissed Apple Smoothie
1 apple
1/2 inch bit of ginger
1 kale (fresh) leaf, destemmed
squirt of honey (local, raw is best)
dash of cinnamon
Whiz in blender until as smooth as it can get - serve it up.
Berrylicious Smoothie
1/2 - 1 cup berries, any kind, single or mixed
1/2 - whole bananna
kale leaf or baby spinach (optional)
squirt of honey
Whiz and serve
Just Peachy
1 peach
handfull of berries, any kind
sqirt of honey
1/4 cup yogurt
whiz and serve
These can all be served as juices too. However, with the smoothies they get all the fiber too. One of our favorite juices is Oranges and Carrots. YUM. Here are some websites that can help you get more "good" foods into your little one. These are raw foodist sites, and as strange as some of the ideas may seem...they work wonders with kids. My kids will eat their weight in kale when we're "massaging" in the oil and juice for Kale Crisps (recipe below)
Lots of recipes, look through and see what might work for you http://www.goneraw.com/recipes
A friend of mine: www.beegreenfoods.com - her son was just diagnosed with Autism and they have severe gluten & casien (milk) intolerances. I've seen the difference diet can make first hand with him as well as my own children.
Kale Crisps:
1 pound fresh Kale, washed well in big bowl
1 lemon, squeezed over kale
sprinkle sea salt to taste
honey or stevia to sweeten (just a little is needed)
Olive or coconut oil just to coat lightly
Massage all together until it's about half the bulk. Lay on dehydrator sheets and dehydrate 6-8 hours, until crisp. OR if no dehydrator, lay out on cookie sheet and place in 200 degree oven for 2-3 hours or until crisp.
Good luck mama. There is so much out there that goes on with our kids that doctors won't tell you about. Some simply really don't know while others don't believe it. Follow your gut instincts until you find a doc who will truly help you. Nutrition is really the key with most issues kids (and adults) have.
Peace!
