How to prepare
- Diet. For 1 to 3 days, food without fiber. Your doctor will give an exact list. The day before, usually only clear liquids.
- Cleansing. Your child drinks the cleansing solution as your doctor directs, and the dose depends on weight. To make it easier, it can be chilled and drunk through a straw.
- Fasting. Before sedation, your child does not eat or drink for a set time. The clinic will tell you the exact hours.
- Talking. Explain in simple words that your child will sleep while the doctor looks at the tummy.

Common questions
My child can't drink all the solution. What should I do?
Call the clinic. Sometimes another plan is chosen, but the preparation cannot be skipped.
