Hello! Poor you, having to watch your child suffer! OH dear.
To solve this problem takes more than a magic bullet, you have to change everything about her diet.
Okay, first rule with constipation, especially hard stools, is that the child is not drinking enough water. Do you have bottled water at home? Make her drink down 4 glasses in between meals. Don't drink a lot of water with meals as it interferes with digestion and absorption. NO iced drinks, no colas. Cold drinks are very ahrd on the digestive system. Herbal tea is excellent.
When she gets up in the morning, have her drink a cup of warm - not hot but warm, easy to swallow warm - water. This induces a bowel movement and cleanses the kidneys.
Have her eliminate all dairy from her diet except one glass of milk before bed, preferably warm milk with a teaspoon of honey. You can also simmer it for ten minutes with a cinnamon stick, 1/2" slice of fresh ginger root, and several whole cloves, then poor into cup with honey. This is a mild laxative. And it tastes GREAT! :)
If you did not breast-feed her, then chances are her intestinal flora was imbalanced and this is a contributing co-factor. She needs to stop eating all sugar, all fruit juices and fruit except for whole green apples for awhile (great fiber and very balanced PH). Cherries, cranberry, and Papaya also okay as whole fruit. The rest are not. Fruit should be eaten alone and never with meals. Limit her fruits and sugars for at least a month. At the same time, have her take probiotics such as Primal Defense to replace the acidopholous in her system.
She shouldn't eat anything deep-fried, and no fats except for olive oil and flax seed oil and vegetable oil.
She could also have a sensitivity to wheat (gluten) and corn. Limit her intake of wheat and flour and corn for one month at least.
So what does that leave her to eat, you may ask? Oatmeal, Quinoa, barley, chicken soups full of veggies (add barley to the soup it's yummy) all veggies preferably steamed, fish, nut butters. You can get pastas made from brown rice at the health food store, and bread without wheat. Rice and rice crackers are great substitutes for bread - just put everything you would put in a sandwhich on a rice cracker or slice of jicama.
Enemas are wonderful on occasion. You can do plain water wtih a little salt (preferably
Sea Salt ), or occasionally do an olive oil implant IF she doesn't have gas or painful belly.
The tablespoon of olive oil at bedtime is a very good idea on occasion.
Do not use laxatives unless she stops having BMs altogether. Since the stools tend to be large and well-formed, it's mostly a diet/not enough water issue. You may simply be expecting to see more fiber than she's actually eating. If she doesn't feel bloated, or stuck, and if her abdomen isn't distended, then she just has slow digestion and the only way to correct that is with diet and exercise. She needs to walk more, play more, ride a bike, do leg lifts and other ab exercises.
Hope that helps!
