What to Do When Your Baby’s Diaper Smells Like Fish

Read the answer first. The Workshop is here only when you want the next step.

Glowing fish-shaped odor ribbon rises from a tied diaper disposal bag while a father phones beside his fully clothed baby.

Has your baby’s diaper started to emanate a fish-like odor recently, leaving you worried and perplexed? You’re not alone! A fishy smell from your baby’s diaper can indeed be startling, but it’s essential to understand that various factors might be contributing to this issue. This comprehensive guide will explain the possible causes of the fish-like smell, whether it’s a temporary or long-term concern, and steps to take for diagnosis and treatment.

Why Does My Baby’s Diaper Smell Like Fish?

Your baby’s diaper might smell like fish due to a condition known as trimethylaminuria, or fish odor syndrome. In this situation, the body struggles to break down a compound known as trimethylamine found in certain foods. The excess trimethylamine is then excreted through body fluids such as urine and sweat, leading to the fishy smell. Dietary factors or a genetic predisposition can contribute to this condition.

Hi Mary-Ann. I have a question: Is method in any way similar to the ones recommended by Dr Bucknam, Dr. Weissbluth or Dr. Karp? We tried those but none of them help.

Hi Regina, thank you for your question. The short answer is no. The techniques I share in my guide are based on newest scientific research and this is why I have never seen any approach similar to the one I recommend.

This method really works! I tried it on my son Jesus and after just one week he went from waking up more than 5 times a night to waking up just once or twice. You are a lifesaver, Mary-Ann!

I just completed your approach and I have to say, it worked almost too well. Yes, it took a bit of getting used to with your bedtime routine but the difference is huge. My son George used to take 1 hours to go down and now he's firmly asleep in no more than 10 minutes! You're the best!

It seems I'm the only man watching this video, lol! What you shared about the 'emotional backpack' made immediate sense to me and I can't wait to help my little girl Mila to unpack it!

Is it Temporary or a Serious Health Concern?

Fish odor syndrome can either be temporary or an ongoing health issue, depending on the root cause. Some causes can be treated effectively, making it a temporary problem. However, if the cause is genetic, the smell might persist, although it can be managed by dietary modifications and proper hydration.

Does it Happen to All Babies?

This fishy smell does not occur in all babies. Since trimethylaminuria is the primary cause, it typically affects babies who cannot break down trimethylamine in their food. Hence, if your baby’s diaper smells like fish, they may have trimethylaminuria and are being fed foods containing trimethylamine.

Long-Term Implications

Fish odor syndrome can lead to long-term psychological and social complications, despite having no other physical symptoms. It can create anxiety for parents and potentially impact the child’s social interactions in the future.

Diagnosis and Treatment Options

Trimethylaminuria is often an inherited condition due to a faulty FMO3 gene. If your baby’s diaper smells like fish, a healthcare professional may conduct urine analysis, clinical examinations, and genetic testing for diagnosis.

Treatment strategies primarily involve dietary changes. Using acidic soaps and giving vitamin B12 supplements can also help. Additional treatments may encompass antibiotics, probiotics, and activated charcoal to eliminate excess trimethylamine from the body. Adequate hydration is also crucial to dilute urine and reduce its odor.

What causes fishy smelling urine?

Fishy smelling urine can be caused by several factors. Consumption of certain foods, like those rich in trimethylamine, can lead to this smell if the body struggles to break down this compound. Other causes include urinary tract infections, certain metabolic and liver disorders, or specific medications. It is essential to consult a healthcare professional for a precise diagnosis if you notice a persistent fishy smell in urine.

What is the fish odor syndrome?

Fish odor syndrome, scientifically known as trimethylaminuria, is a rare metabolic disorder. Individuals with this condition cannot convert trimethylamine, a chemical compound present in certain foods, into a compound that can be easily eliminated from the body. Consequently, trimethylamine builds up and is released in sweat, urine, and breath, giving off a strong fishy odor. This condition can be temporary or chronic, based on its cause, and it can be managed th
