Dr. Mommy’s Magic Butt Paste
very once in a while, being a pediatrician mom comes in handy. I’m not talking about those times when the other mothers are worried about the sugar content of infant formula, and you’re like puleeze, forget sugar! I’m more worried about neuroblastoma, histiocytosis X, and rheumatoid arthritis! My pediatric background ratchets up the worry meter by a thousand fold. Those times it isn’t handy to be a pediatrician. It’s freaking terrifying.
No, I’m talking about the rare time when you actually remember something from your little kid medicine training that helps your child get better, for real. That’s what happened this weekend.
The diarrhea started at the end of last week. It wasn’t horrific. There was no fever, vomiting or blood in the stools, so I wasn’t freaked out or anything. I did the usual BRAT diet minus the R and T and continued to feed through. So the diarrhea was pretty manageable despite several diaper blowouts. What was not manageable was the diaper rash.
We’ve been pretty darn lucky that we’ve never had to deal with a bad diaper rash. During my training, I saw so many kids with excoriated bottoms that I was counting the days until Zara had one that got superinfected with fungus displaying those lovely satellite lesions. But lucky for us, this never happened.
After the development of the shits, as I like to call it, Zizi’s bottom became redder than a radish. I used Desitin, Aveeno diaper ointment, and even the Whole Foods approved Weleda diaper ointment. Nothing helped. And she screamed bloody murder every time we had to change her.
Finally by Sunday when her skin was starting to break down, I started to get a little stressed. And that stress managed to cause one of my long buried synapses to fire. A memory returned. What about butt paste? I thought. Yeah, that might work.
Now I’m not talking about the Boudreaux Butt Paste. I’m talking about the Butt Paste remedy passed down through generations of pediatric residents. I’m talking about the good stuff.
Every pediatric facility or ward has their own way of making Butt Paste. Ours consisted of the following:
- 2 oz A & D ointment
- 2 oz zinc oxide ointment
- 1 oz Maalox or Mylanta
- 1 oz bacitracin
This is the real Butt Paste!
I hightailed it to RiteAid and got my supplies. I stopped at the pharmacy and asked for a screw top jar for me to mix and store my concoction. When I spoke to the pharmacist, he tried to convince me to get the Butt Paste on the shelf, but no. I knew that the antacid was the special ingredient to soothe the pain. I was going to make the good stuff.
AdoringHusband watched my chemistry project as I worked. “Why doesn’t this come premade?” he asked.
“No idea,” I shrugged.
“Well if it works so well, someone should make it”
“Yeah, you’re right,” I replied and kept mixing.
I got just the right consistency to make me happy. So we gave it a go. We soaked Zizi’s butt in a warm bath with baking soda and then gently dried her off. Next (it was like a surgical procedure) we returned to the changing table (the place of howls) and got set up for the application. AdoringHusband was on distraction and I was on application. I touched the mixture to her skin and waited for the shrieks. Nothing. AdoringHusband and I looked at each other quizzically. Zara was playing with her feet, unfazed. I finished my application without incident.
Later in the evening, we did the same thing again. This time, some of the broken down areas of skin that weren’t holding the mixture very well had improved. She was starting to heal. And this morning? She was 80% better. AdoringHusband became a disciple of the real Butt Paste.
He’s already trying to come up with a business plan to sell Dr. Mommy’s Magic Butt Paste. He’s created a jingle that he spent the morning singing to Zara. Zara’s face will be on the jar. “Who will be able to resist?” he asked happily.
All I can say is that sometimes a little pediatrics comes in right handy. Mommy made it better.

























Hmmm. If you only knew someone in the drug manufacturing industry to get you an “in.” Wait a minute…
Seriously, though, it sounds like a great idea. You should take the recipe off the blog and totally market that and make MILLIONS! My sis used to put strait maalox on my nephew’s diaper rash when it got that bad and it worked to soothe it, but this stuff sounds amazing.
Now can I interest my lovely company in such a product? Hmmm…
I hope and pray I never have to use it but if I do….. I’ll be mixing it up.
You had me at the name.
Now you owe me a new keyboard. Old one’s coffee damaged.
What is A & D ointment?
what is the purpose of the zinc oxide? I’m assuming you’re performing this task inside and so sun block is probably unnecessary.
Thanks for the info.
Magic Butt Paste – that is too over the top!
L & M, making the world a better place, one butt at a time.
I think it’s catchy too!
A+D ointment is petrolatum and lanolin to act as a moisture barrier. The Zinc Oxide helps heal irritated skin.
Who knew????? I have tried so many different products for diaper rash-I will add this to my bags of tricks. I say go for it and manufacture it! Thanks for your “secret recipe”.
So promise me that when I become a mommy you are still around to give me the recipe to your secret, magical butt paste (and to help me when I am worrying if my kid has histocytosis X)
Hey, leave the histiocytosis X worrying to me!
brilliant! A & D is the only thing i can use when Sam has the bad butt- which has only been 2x, but those howls of pain make you run for something better than balmex!
I just put that in my file for the future. I have no idea if I’ll ever be lucky enough to need it but if I do, I’ll have Dr. Mommy’s Magic Butt Paste Remedy to hand!
Now what’s this about histocytosis x?
Flicka’s last blog post..Sleep gynecology and my own personal cheering squad
Don’t even ask about histiocytosis X!
I am wondering what class at Harvard Medical School my sister missed where they discussed this recipe, which makes PERFECT sense. Wow. I can’t even fathom that I have never heard of this before. I am telling our mom! Seriously…my sister specialized (at least for a while) in little kids/babies…and her best advice for the only one of my three kids who got a diaper rash pretty badly (in the hospital at her birth, no less), suggested going diaperless was the best solution.
Do you have any remedies for the hivey skin my 4.5 year old son still gets (He was a 36 weeker, not asthmatic, but has had a few breathing issues at times) gets every time he is about to have breathing/cold-like issues?
I think Adoring Husband is onto something — and I would take down your recipe and patent it. Honestly. Lord knows how much of the other stuff moms and dads have purchased, to no avail.
Courtney: I have no idea how your comment got snagged as spam! I’ve restored it.
About the recipe, it’s funny how I didn’t even remember it until the stress kicked in and made my brain work a little bit.
I wish I had a good answer about the hivey skin. Sounds like a good emollient (and creams are better than lotions) but the problem is that much of the stuff you would put in for anti-itching will get absorbed through the skin and can become problematic for little people. Some people do swear by calendula containing creams for rashes and itching, but I don’t have another good remedy from residency.
Ahh. The paste I heard of was balmex, clortrimazole, and neosporin. But then I have to wonder if the clortrimazole and the neosporin would cancel each other out.
But I do have to give a shout out for the clortrimazole — it seems fully 1/2 of the rashes around my house end up being yeasties. (Thank you, thank you to the experienced mom in the bathroom at the Ben & Jerry Factory store in October of ‘98!)
What the heck is histocytosis X? Do I even want to google that?
Meira’s last blog post..Bullet points
Hey Meira: the clotrimazole and neosporin wouldn’t cancel each other out. But I think you should sort out whether the rash is fungal or not before shotgunning (as we call it in medicine) with both. If fungal, then antifungal, if not a topical antibiotic to prevent bacterial superinfection is warranted. But Zizi’s rash was absolutely not fungal. There were not satellite lesions or other signs that look like fungus. Just irritation from the shits…that’s all.
And no, you do NOT want to google histiocytosis X!
Poor baby. I hate when my kids are sick.

Ah, Maalox on a raw bum works miracles. I had to whip up a similar paste several times with my oldest. Funny thing is, I’m a med school grad (put off residency to be a mommy), who happened to tormenting myself over whether my youngest child’s weird persistent rash and horrific cradle cap was really histiocytosis X… The things too much education can make a mom worry about!
Nice post!

I’ve passed your “recipe” on to my sister-in-law for my new niece, wish I had had it for my two girls when they were babies. Our pediatrician always recommended covering the clortrimazole with Aquaphor. Aquaphor is great because it’s water based and is easy to clean during diaper changes…..
I had to post a late comment and say “you are a genius!” My little man developed a horrible rash overnight thanks to a bout of the runs. I remembered your post and whipped up the concoction. This morning, he was 100% better and didn’t make a noise when Daddy changed his diaper. Thank you so much

I’m so glad to hear that it worked for you, Irshlas!
Teendoc,
This was great! I’m going to save this recipe for our future use. DD has a rash right now, she’s only had a couple bad ones, but this is one of em… I’m going to try your Mommy’s Magic Butt Paste. thanks for the tips!

I knew the day would come that I’d need this. And now I am off to CVS and I thank you for your archives . . . !
I stumbled across this around the beginning of the year when my daughter had a terrible diaper rush, with open blisters. I mixed this up using the directions above and it was gone in a day or two, it worked better then the 4 prescription creams her Ped. gave her. In my opinion the best Zinc Oxide to use is the Desitin Original, not the creamy, because it has 40% Zinc Oxide, the highest you can buy over the counter without prescription. All the rest have 10 – 12%. We use this after every diaper change. It hasn’t prevented her for ever getting a diaper rash, but is has cured everyone one is less then 48 hours.
I’m so glad that you found this butt paste to be useful. And yes, you must use the regular Desitin and not the creamy.
When we were in training, this paste was only used for treatment of severe diaper rash and never for prevention. I’ve been using the new Balmex powder (that has zinc oxide) as a preventive with Zara with good results, but she is getting older and is using the potty more, so that may be a factor as well.
