TIL that splattering your scrubs with beet juice at lunch leaves you looking like you were at a VERY bad C-section. And it doesn’t blot out. So now I look like an axe murderer, taking care of the babies.

Encouraging a kid who decided to get vaccinated, in my own apparently strange way. #PedSky
Former pediatrician here (now just newborns) — congratulations and thank you.

When you feel sore and achy afterwards, remember that it’s because IT’S WORKING! Your body’s immune system is going “what the heck is this stuff?!? I’m going to learn to kick the sh*t out of it if I ever run into it again.”

Whenever I got my shots and I DIDN’T feel sort of crummy the couple of days afterwards, I was worried the shots weren’t working :)

Was working with a medical student recently who said I had a “moral code”. I don’t really know what that means but I felt strangely disturbed. They probably shouldn’t let me work with medical students. I’m contaminating them.

Thank you, Massachusetts Department of Public Health. #PedSky
Massachusetts Department of Public Health (DPH) 
Guidance on Recommended Reference Materials for Pediatric Immunization Schedules  
January 2026 
 
The Massachusetts Department of Public Health (DPH) is issuing this notification to inform clinicians of a change in recommended reference materials for pediatric immunization schedules. 
 
DPH has a longstanding and ongoing commitment to promoting evidence-based immunization practices that protect communities from vaccine preventable illnesses.  Following a review of recent changes to the Centers for Disease Control and Prevention (CDC) pediatric immunization schedule, DPH now recommends that clinicians in Massachusetts use the American Academy of Pediatrics (AAP) Recommended Child and Adolescent Immunization Schedule  as the primary reference for the routine immunization of infants, children, and adolescents. 
 
DPH recognizes the importance of clear, consistent, and evidence-based guidance to facilitate safe and effective vaccination practices. AAP is a national professional organization representing pediatric physicians, and its immunization schedule is developed by pediatric experts and updated regularly to reflect current evidence and clinical best practices for immunizing children and adolescents. The AAP immunization schedule aligns with science-backed pediatric standards of care and provides detailed guidance that supports clinical decision-making in pediatric settings. 
 
Clinicians should continue to follow all applicable state requirements, including the immunization requirements for school and camp entry (aligned with AAP recommendations), and reporting obligations, including documentation of administered immunizations in the Massachusetts Immunization Information System (MIIS). 
 
DPH will continue to monitor national immunization policy updates and will communicate any additional guidance as needed. 
 
Thank you for your continued commitment to protecting the health of Massachusetts children and families. …

Challenger 650 for X-Plane sim is picky… tried high altitude flight for the first time at 36,000 feet. I might have accidentally deactivated cabin pressurization + climate control. So, the passengers might have all passed out and the cabin might be at -3°C. No repeat customers from this flight.

I ignored the strip.clip argument in #ggplot2 for way too long 😲 Combined with a small negative margin tweak, you can place facet labels inside each panel. A tiny trick that makes small multiples feel so much cleaner. 🔵 no manual coordinates 🔵 inherits theme styling 🔵 scales nicely when resizing
Side-by-side comparison of two multi-panel bubble charts faceted by world region. The left column shows the default facet labels placed above each panel (“Africa”, “Americas”, “Asia”, “Europe”, “Oceania”). The right column shows the same charts, but the facet labels are moved inside each panel at the top-left using a negative margin. In the center, there is a title reading “Want to place your facet labels inside each panel?” with an arrow pointing right, followed by a short ggplot2 theme code snippet demonstrating how to move strip text inside the panel.
