As of 11/10/25, we are recommending discontinuing use of ALL ByHeart infant formula, not just the affected 2 lots originally published as I have a concern there will be more and Infant Botulism is too serious to risk it. We are recommending Nara Organics as my new favorite anyways and have some large sample containers at the office. My patients can contact the office and we'll give them out on a first come, first served basis. I recently met with the CEO of Nara and am very impressed by her formulation.

Introducing a whole new standard for infant formula. Nara Organics is built on the healthy fats in organic whole milk.

Hello all. It's been a wild and wacky ride in the Public Health world lately, especially as we approach the winter season, so I just wanted to remind my families that I am recommending the Flu vaccine. I give the Fluzone preservative free and even when it isn't a perfect match it's really been so helpful for preventing complications from influenza. I keep internal statistics in the office and my patients unvaccinated for Flu have higher rates of serious bacterial pneumonias and antibiotic use in the winter. So giving a flu vaccine (and a pneumonia vaccine, when eligible) helps to protect your microbiome in the long run.
I will also have COVID vaccines in the office- please reach out to schedule as these do require more planning. The Novavax vaccine is a great option for those 12 and up and we will have it available in the office soon.
Marin Public health is predicting RSV any minute, with Flu peaking a little later, and COVID after the new year, so now is the time to get your winter protection on board. I found Halloween the last two years was the ultimate super spreader event for Influenza and it was the week after that I started seeing a significant number of Flu cases.
My patients, as always, can reach out at any point for personalized vaccine guidance. Wash your hands, stay well, and don't forget your Vitamin D!
Katelyn Jetelina made a updated infographic which I think is helpful for navigating all of this, see below.

I have stayed away from the Tok, and haven't used Instagram for patient information, instead preferring to communicate directly with my patients so that my advice can be personalized. However, right now there's a disturbing micro-trend happening on social media regarding breastfeeding. There is misinformation circulating that there's no benefit to nursing beyond six months. I was chatting with one mother about this in a visit and clearly her phone was listening because she reported back to me a day later that she was being served up a load of information that breastfeeding beyond 6 months didn't matter (Insert appropriate garbage emoji here).
Feeding a baby mother's breastmilk, in whatever form you can, for as long as it works for you, is one of the best things you can do for your baby. It prevents infections, diabetes, and even cancer in your child. Did you know that it also prevents cancer for the breastfeeding mother? It's also one of the best things you can do for your baby's microbiome. Breastfed babies have shorter milder infections and are less likely to need antibiotics.

Have you seen misinformation about breastfeeding online? How could this be corrected? I have zero interest in being a social media pediatrician but this might motivate me...

Love this article from ADDItude about girls and ADHD, that also makes a great point about treatment in general: Treatment isn't binary. It's not medication or nothing. Over the years ADHD has become a big part of my practice because there are so many integrative options to improve quality of life. For someone who likes to think about the whole picture it's really a joy to treat.

Good news! Transitional Kindergarten is back on for Mill Valley. See district details below. Registration starts tomorrow and I recommend registration as soon as possible if you want a TK spot for your child. I'm a big fan of Transitional Kindergarten.

As part of this extension, the district will open registration for the TK program on March 26, 2025, for the 2025-2026 school year. Children who turn four years old by September 1, 2025, are eligible to enroll. While registration will remain open, we encourage all families who plan to enroll their children to do so during the initial round of registration, which will end on May 2, 2025.

Marin County Public Health just let county providers know that we are experiencing a cluster of recent overdose deaths in the county, likely due to other drugs being laced with Fentanyl. They have found increased Fentanyl and Methamphetamine in our wastewater currently.
Please remind your kids about the risks of putting any unknown substance into their body. The risk from Fentanyl scares me even more than the mental health risks like psychosis from Ma*****na.
We have conversations about these risks in the office, but parents I encourage you to discuss these topics again and again with your kids. Make sure they know the risks, and if they are going to use substances, there are options that are lower risk than others. These issues absolutely apply to everyone, in every socioeconomic group.
For those who do choose to use substances, OD Free Marin also has resources like fentanyl testing strips, and free Narcan, a lifesaving drug that can be administered as a nasal spray by just about anyone, in an emergency.

NarCAN® (Naloxone) The Lifesaving Opioid Overdose Reversal Medication Where Can I Get NARCAN® (Naloxone?) NARCAN® (naloxone) is available without a prescription (over the counter). Please call ahead for availability and pricing. NARCAN® Vending Machines (FREE) Marin HHS Social Services Courtyard...

In his State of the City address, Mayor Eric Adams (D) said social media companies are fueling a mental health crisis with “addictive and dangerous” products.

Marin County Public Health announced new county safety data today about use of Electric Bikes.
Youth 10-19 are disproportionately impacted by E-bike accidents and 71% of calls for bike accidents in this age group are E-bike related and unsurprisingly, injuries are more severe.

If you're considering an E-bike for the holiday season know that Class 1 E-bikes are significantly safer. Here's a link to a free E-bike safety course put together by CHP. I suggest you watch it and come up with a safety contract for your rider. My 12 year old is NOT getting an E-bike any time soon.

P.S. We were able to secure more doses of preservative-free Flu vaccine for the office so those of you I turned away reach out if you'd still like a dose. Influenza A has already arrived and the vaccine is a good match for the circulating strains.

Electric Bicycles (E-Bikes) are a growing trend that allow riders to bike at higher speeds and travel greater distances. With the increase in E-Bike popularity, the need for safety education and training is essential. Click on the link to take the E-Bike training under the “Electric Bicycle Tra.....

RSV is here and this arrived today.

Happy Back to School season! Respiratory viruses seem to be everywhere. We have sent out a seasonal update in Elation to all our patients and I will be holding a Zoom chat next week at noon on 9/6 to go over what I’m recommending for this fall and winter in terms of treatment and vaccines such as Flu, COVID and RSV. Patients please sign in to Elation or text us on Spruce for the info. If you can’t attend please send your questions ahead of time and I’ll get to them. The session will also be recorded.

Naming emotions with children is a simple but very powerful tool. Love this.
