M.O.P. for Ages 3 to 10

Parents often tell us, "My 4-year-old is pee trained but not poop trained." Or, "My 8-year-old still isn't night-time potty trained."

In reality, these kids are trained. Accidents, whether daytime or nighttime, have nothing to do with "training" or stress or wilful behavior. Enuresis (wetting) and encopresis (poop accidents) are caused by chronic constipation.


No amount of training or bribery will help, because accidents are out of these kids' control. The enlarged, stool-stuffed rectum is pressing against and aggravating the bladder nerves. In the case of encopresis, the stretched rectum has lost tone and sensation, so poop just drops out of the child's bottom, without the child even noticing.

You cannot assume a child will just "outgrow" these conditions. In fact, we work with so many teenagers who have enuresis and/or encopresis that we started a support group just for parents ages 11+.

What makes accidents stop? The enlarged rectum must be cleared out on a daily basis for several months, allowing it to shrink back to size, regain tone, and sensation, and stop bothering the bladder.

That's what M.O.P. accomplishes.

This 30-second video explains why M.O.P. works.

The Anthology provides detailed instructions on implementing M.O.P.

Frequently Asked Questions About M.O.P.

What does M.O.P. stand for?

The Modified O'Regan Protocol. The regimen was developed in the 1980s by Sean O'Regan, M.D., a pediatric kidney specialist at Sainte Justine hospital in Montreal, who sought to resolve his own son's bedwetting. The regimen was "modified" by Steve Hodges, M.D., a pediatric urologist at Wake Forest University. Dr. Hodges named the regimen after Dr. O'Regan, whom he considers a genius.

What exactly does M.O.P. involve?

M.O.P. is more of a process than a strict protocol and involves trial and error. The gist: •Phase 1: One enema per day for at least 30 days and until at least 7 days of dryness (day and night). •Phase 2: Taper to one enema every other day for at least another 30 days. •Phase 3: Taper to two enemas per week for at least 30 days. •Phase 4: Take a daily osmotic laxative throughout M.O.P. and for at least 6 months after. The type of enema and laxative you choose depends on what works best for your child. Count on some experimentation to figure that out. The numerous options are spelled out in The M.O.P. Book: Anthology Edition. Keep in mind that many children require more than 30 consecutive days of enemas to reach dryness. This is especially true for those who have daytime accidents as well as bedwetting. M.O.P. is not a quick fix. It can take many months for a chronically clogged rectum to be cleared out, for a child to overcome the withholding habits, and for the rectum to shrink back to size and stop aggravating the bladder nerves.

Are enemas really necessary? Are daily enemas even safe?

Yes and yes. For most kids with enuresis and/or encopresis, oral laxatives are inadequate, offering temporary improvement at best and sometimes making accidents worse. Dr. Hodges' research clearly demonstrates that enemas are far superior to laxative treatment. As for safety, many physicians tell parents that enemas cause dependence, electrolyte imbalance, and emotional "trauma." All these concerns are unfounded, as we discuss in great detail in The M.O.P. Book: Anthology Edition.

How can I be sure M.O.P. works?

You can read Dr. O'Regan's studies and Dr. Hodges'. They are posted in full on our Research page. If the studies make your eyes glaze over, try these blog posts: New Study: Daily Enemas Resolve Pee Accidents Far Better Than Miralax •The Only Reliable Bedwetting Treatment Finally Gets Its Due The fascinating story of Dr. O'Regan's discovery and research is told in the M.O.P. Anthology. You can find a l ist of medical professionals on board with M.O.P. on our Find a Provider page.

What if my doctor is not on board with M.O.P.?

It's helpful to have a doctor in your corner, but it's not necessary. Many doctors have no experience with enemas and are downright hostile to them, in which case we recommend giving your doctor The Physician's Guide to M.O.P. The guide is included in the M.O.P. Anthology and can be downloaded separately on our Charts & Guide page. Most families who implement M.O.P. do so without their physician's support. Many of them join one of our private Facebook support groups to get input ad reassurance from Dr. Hodges and other parents experienced with M.O.P. Another option is to have a 30-minute, one-on-one Facetime, Skype, or phone consultation with Dr. Hodges.

What if there's no way my child will agree to enemas?

That's what most parents think! But you'd be surprised. Most kids are more bothered by accidents than they let on and are willing to give M.O.P. a try. Before long, enemas become routine. Many kids actually ask for their enema each day because they feel so much better. This blog post will help: 13 Ways to Ease Your Child's Fear of Enemas . Also, we highly recommend that all kids ages 10 and under on M.O.P. read Bedwetting And Accidents Aren't Your Fault. Most kids think they are the only one having these issues. They find the books very reassuring, and parents report their kids are more likely to comply with treatment when they read the book.
