Symptoms, Treatment, and Recall Facts
A nationwide recall of ByHeart Whole Nutrition Infant Formula was issued due to rare cases of infant botulism linked to the product. Infant botulism is a rare illness caused by toxins from Clostridium botulinum bacteria that can affect a baby’s nerves, movement, feeding, and breathing. If your baby consumed ByHeart formula recently, stop using it immediately and watch for early signs including new constipation, weak or changed cry, difficulty feeding, reduced facial expressions, and a floppier feeling when picked up. Seek emergency care if your baby shows any signs of breathing difficulty or severe weakness. Most babies who consumed ByHeart formula will not develop symptoms. When caught early, infant botulism is very treatable and most babies recover fully with prompt medical care.

Some parents hear the word “recall” and immediately picture the worst. If that’s where your mind went, you’re not alone. Parents all over the country are double-checking cans, replaying the last few days, and asking themselves if their baby is okay. These feelings show up fast and loud, but with clear information, it becomes much easier to know what to do next. Just this week in clinic, I met a mom whose breastfed baby had recently become fussy at the breast. Exhausted and overwhelmed, she decided to switch to formula. She tried a few, landed on ByHeart, finally saw her baby settling, and felt a little relief. Five days later, the recall notice came out. The look on her face was a mix of fear and guilt that most parents immediately recognize. She kept asking, “Is he ok? I stopped as soon as I heard about the recall.” The truth is: he was completely healthy, but her mind went straight to the worst-case scenario. And she’s not the only one. When recalls hit, parents often jump straight to fear before they have all the facts. So let’s walk through what botulism actually is, what signs to look for, and what this recall really means for your baby’s safety.
What Is Botulism in Babies?
Infant botulism is a rare illness caused by a toxin produced by the bacteria Clostridium botulinum. In babies under one year, the spores can settle in the intestines, release toxin, and affect the nerves that control movement, feeding, and breathing. It sounds alarming, but here’s what matters: When caught early, infant botulism is very treatable, and most babies recover fully. Most cases come from environmental spores in dust or soil, not from formula. Honey is another known source, which is why all pediatric organizations recommend avoiding honey until after a baby’s first birthday. Formula-related cases are extremely rare, which is why the ByHeart recall has gained so much attention.
Why Infant Botulism Happens
Environmental Spores: Spores naturally live in dust and soil. Babies may swallow them accidentally during everyday life. This has nothing to do with hygiene or anything a parent “did wrong.” Honey: Honey and honey-containing products can carry spores. Avoid honey until after one year of age. The ByHeart Formula Recall: Recent cases of infant botulism prompted a nationwide recall of all unexpired ByHeart Whole Nutrition Infant Formula. The recall is precautionary and meant to protect infants while testing continues. Most babies who consumed ByHeart remain completely healthy.
Signs and Symptoms of Botulism in Babies
Botulism often appears slowly over several days. Early signs can be subtle, so knowing what to look for helps you act quickly if needed.
Early Signs: These are usually the first clues:
- New constipation
- Weak suck or difficulty feeding
- Milk leaking from the corners of the mouth
- A quieter or weaker cry
- Less facial expression or reduced eye contact
- A “heavier,” more floppy feeling when picked up
If these symptoms appear together, call your pediatrician the same day. Progressive Signs: These require urgent medical evaluation:
- Trouble holding the head up
- Weak arms or legs
- Droopy eyelids
- Difficulty swallowing, coughing, or choking with feeds
- Fast, shallow, or labored breathing
If breathing looks abnormal, treat it as an emergency.
What Happens If a Baby Has Botulism?
Hearing the word “botulism” is scary, but even in the rare case a baby develops it, treatment is well-established and outcomes are excellent with early care. Doctors act quickly based on symptoms; they don’t wait for long test results.
BabyBIG (Botulism Immune Globulin): BabyBIG is the main treatment. It’s an IV medication that neutralizes the toxin and prevents the illness from progressing. Babies typically improve over the following days and weeks.
Supportive Care: The medical team may:
- Support feeding if sucking or swallowing is difficult
- Monitor breathing closely
- Provide respiratory support if needed
- Use physical and occupational therapy to help strength return
Recovery takes time, but most babies go on to do very well. Knowing there is a clear plan brings comfort during a frightening moment.
What To Do If Your Baby Used ByHeart Formula Recently
If your baby had ByHeart formula in the last thirty days:
- Stop using it immediately.
- Watch for the signs listed above.
- Call the pediatrician the same day if you notice anything concerning.
- Seek emergency care if your baby has breathing difficulties or severe weakness.
Most infants will not become ill. A healthy baby today is a very reassuring sign.
When Guilt Takes Over
The mother I saw in clinic truly believed she failed her baby. She had been breastfeeding for weeks, pushing through exhaustion, until she simply couldn’t continue. Switching to ByHeart wasn’t a careless decision. It was a survival decision, and her baby finally seemed content. Then the recall notice appeared. She held her baby, apologizing for something she could never have predicted. Meanwhile, her baby looked strong, fed well, moved normally, and had a bright cry. Every clinical sign pointed to a healthy infant. What she needed wasn’t sugar coating. She needed clarity: “You didn’t cause this. You acted with love, responded quickly when new information appeared, and your baby looks good today.” Most parents in her situation go straight to that same place in their mind. It’s a natural response. Clear information just gives you something solid to hold onto while you figure out the next steps.
Why Guilt Shows Up So Fast
Parents tend to replay choices and imagine they “should have known” something before they ever could have known it. This isn’t failure. It’s caring deeply. Your brain jumps to worst-case scenarios because newborn life is unpredictable and overwhelming. But you can gently shift your focus to what’s actually in front of you. If your baby is:
- Feeding normally
- Crying normally
- Moving their arms and legs
- Holding their head as expected
- Breathing comfortably
These are strong signs they’re well today. Today is what matters.
One Thing You Can Do Right Now
Choose one simple action today: Check how your baby is feeding and moving. If they look like themselves, you can exhale a little. Keep an eye on them over the next few weeks, but you don’t need to watch them with fear. You just need to stay aware.

If something feels off, your pediatrician wants to hear from you. You are never bothering anyone.
The Wrap Up
Botulism is rare, even during a recall, and most babies who consumed ByHeart formula will never develop symptoms. You now know the early signs, you know when to call the doctor, and you know what a truly concerning symptom looks like. If you’re carrying guilt right now, pause and look at your baby. If they’re eating well, moving normally, and acting like themselves, you can breathe. You acted quickly, you’re paying attention, and you’re doing everything right. You’ve got this.

If this eased your worries, share it with another new parent. And if you want a safe, judgment-free space to talk, the Support Circle is waiting for you.
