Anal Dilation

What do I need to do my baby's dilation?

• Dilators
• Lubricant
• Pad or diaper
• Diaper wipes

How often should I do the dilation?

As indicated by your doctor.

When should I do the dilation?

Choose a time of day that is easiest for you. Most parents find it easier to do the dilation when there is another person available to help. If you are doing dilations more than one time per day, do one in the morning and one in the evening.

How do I do the dilation?

It works best to do the dilation with your baby on the diaper changing table. Put a clean diaper or cloth under the baby's bottom. Hold the baby's feet and ankles in one hand over the baby's stomach so you have a clear view of the anus. Lubricate the tip of the dilator. Start with the smaller dilator. Hold the dilator like you would a pencil. Gently push the dilator about 1 to 1.5 inches into the anus. If this goes easily, then lubricate the next size dilator (if you have been told to do so) and repeat the dilation. As the dilator passes you may feel a slight "popping" feeling.

What will my baby feel?

Your baby may feel a small amount of pain during the dilation. Most babies grunt or push against the dilator because it causes the feeling of needing to stool or poop. Many babies will stool during the dilation. Once the dilation is done your baby should not be in any further pain. You may give Tylenol one hour prior to dilations for pain. Follow the Tylenol label for dosing.

What can I expect after the dilation?

Your baby should stool easily after dilation. You may see a small amount of blood at the time of dilation and with the next stool after. Bleeding should not continue.
