High-Fiber Diet

• Fruits such as peaches, grapes and pears will help your child develop stools that are easier to pass stool. You can also try prune juice, but your child may not like the taste. You also can try white grape or pear juice.
  
  High-fiber foods such as whole grain breads, beans, sweet potatoes, or cereals can also help relieve constipation. According to the Mayo Clinic, you should limit foods such as cheese, meat, or processed foods (such as sugary snacks). Too much cheese can cause a bulking effect in your child's intestines, which can lead to constipation.
  
  

Fluid Intake

• Children need at least two to three glasses of fluids a day, which can include water or fruit juices. Fruit juices should not contain large amounts of sugar, or should be slightly watered down. If your child is drinking large amounts of milk, have him cut back. According to Keep Kids Healthy, having too much milk can lead to constipation. On the other hand, soy milk helps soften stools.
  
  

Bowel Training

• Forcing a child to learn to use the restroom before she's ready can cause fears of going, and she might avoid it in order to gain control of her body. To combat this behavior, wait for your child's queue to let you know when she's ready. When the time comes, have your child sit on the potty for 10 minutes a day after eating. Bowel training works best after meals, since this is when your child is likely to produce a bowel movement.
  
  

Rewards

• Use a reward program when you begin bowel training. Children respond well to being rewarded for their efforts, even if they don't succeed. You can use a chart with stickers, letting your child put a sticker on the chart when he goes potty. You also can sing a special song and do a dance to show you appreciate his efforts. Older children may respond better to bigger rewards, such as a trip to the zoo or park.
  
  

Laxatives

• Laxatives are a last resort. They should only be used when constipation becomes so severe that your child has been unable to pass a stool for more than four days. Consult with your child's pediatrician about what kind of laxative is safe. Never administer a laxative without knowing if it can potentially harm your child.
