Many things can cause a child to itch that part of their anatomy.
One of the more frequent causes is pinworms, but other causes are chafing, hemorrhoids, a yeast infection, or poor hygiene. If your doctor confirms it's not anything serious, here are some tips to give your child a bit of relief.
Keep the area dry.
Moisture can cause irritation if you don't keep your child's bottom dry. It could also create an environment for a yeast infection to grow. Also have your child change underpants several times a day (3-4 times) and remove underpants for bed time, if possible.
A cornstarch powder will work very well for keeping a child's bottom dry. If you do use any sort of powder, shake it into your hand and apply to the bottom. Don't just shake it at the bottom, because inhaling the powder could be irritating to your child's throat and lungs.
Itching could be due to not properly wiping. Dry toilet paper does not get the anal area clean enough, so try teaching your child to wet the toilet paper slightly before wiping, or provide a supply of wet wipes to use. Following using moist wipes, be sure the child also dries off the area with dry toilet paper, to prevent excess moisture. It could also be handy to have the child bathe after each bowel movement.
Push the Fiber
Hemorrhoids usually don't cause anal itching in children. However, if the doctor diagnosed your child with a case of hemorrhoids, you need to add more fiber to your child's diet. Increase the amount of fruit, vegetables, and whole grains, and decrease cake, candy, cookies, and potato chips. Not eating enough fiber causes constipation, and straining to make a bowel movement can cause hemorrhoids. Also make sure your child drinks plenty of water.
Draw a bath (with only a few inches water) and add three to four tablespoons of baking soda to it. Have your child sit in the water for 15 minutes. These baths can be very soothing to an itchy bottom, no matter what is causing the itch.
Another idea is to add a packet of Aveeno Bath Treatment to your child's bath. It's also soothing.
Add some Gel Protection
Itch-X, Vaseline, or Desitin can protect and soothe the itchy area.
Add an Extra Rinse
Traces of laundry soap could cause itchiness. Put your child's clothing through an extra rinse cycle and see if that takes care of the problem.
Also, stop using fabric softener, as this can irritate some children's skin.
When to See the Doctor
See the doctor if the itching is paired with weight loss, lower appetite, or upset stomach. Also see a doctor if there is a rash that is raw or oozing, or if there is fever or nausea that could signal an infection. If your child has pinworms, a yeast infection, or hemorrhoids, the doctor can usually prescribe something to help the itching and the condition.
