E.M.
M., may I suggest that you look at what you are feeding her and how much fluid she is getting. Are you giving her vitamins? Iron supplements can cause constipation and so can an allergy to dairy products. You might try calcium fortified Soy Milk. Also, oatmeal, fruits and veges will give her the fiber she needs to help keep her digestive system healthy. Instead of offering her just juice or milk, offer her water. There is a great article on this page about constipation and how to train the bowels, as well as tips on helping her with her fear of pooping.
