If your kid plays a sport and is also a picky eater — this episode is
for you.

ARFID (Avoidant/Restrictive Food Intake Disorder) is showing up more
and more in young athletes, and the patterns almost always start years
before anyone names them. The 14-year-old recovering from her second
stress fracture? Her food restriction started at age three or four.

In this episode, I sit down with Katie Syvarth, RD, CSSD — a board-
certified sports dietitian based in Kentucky — to walk through what
ARFID actually looks like in young athletes, why under-fueling and
stress fractures so often travel with it, and what parents of young
picky kids should be paying attention to right now — long before
anyone is talking about diagnoses.

We trace Katie's case study of a teen athlete recovering from her
second stress fracture all the way back to age three. The signs were
there. They're often there for the kids in YOUR home too — they just
look small at the time.

WHAT YOU'LL LEARN:
- How ARFID is different from typical picky eating in athletes
- The "food funnel" — when the list of safe foods gets shorter, not longer
- Why under-fueling and stress fractures often travel together
- Why ~90% of young athletes are under-fueled (and what to do about it)
- How sensory issues, ADHD, autism, anxiety, and OCD overlap with ARFID
- What to do at the table TODAY with your young, picky athlete
- Why pressure tactics backfire (and what works instead)
- How to advocate for your young athlete if you're not being heard
- How to find an ARFID-informed dietitian or therapist

ABOUT KATIE SYVARTH, RD, CSSD:
Katie is a board-certified sports dietitian and the founder of Nutrition
at Play, based in Kentucky. She works with athletes of all levels — from
high school competitors to endurance athletes — on under-fueling,
disordered eating, body image, and ARFID. She blends performance nutrition

If the idea of introducing peanut butter to your baby sends your heart rate up — this episode is for you.

As a pediatrician and registered dietitian, I've sat across from families who are genuinely terrified of allergen introduction. Their fear makes complete sense. But fear doesn't get the final vote. A plan does.

In this episode, I walk you through two real families from my practice, the landmark science that completely changed how we introduce allergens, and exactly what to do based on your baby's individual risk — so you can move forward with confidence instead of anxiety.

In this episode:
✔ Why the old "delay allergens" advice tripled peanut allergy rates — and how the science did a full 180
✔ The LEAP trial: what it found, why it matters, and what 86% risk reduction actually means for your family
✔ The dual allergen exposure hypothesis — why your baby's skin is the real risk factor (not family history alone)
✔ Eczema and food allergy: what the connection is and why I treat eczema aggressively from the very first weeks
✔ Exactly how and when to introduce peanut butter and egg at home — by risk category
✔ Myths I hear every week that have no evidence behind them — including breastfeeding, hypoallergenic formula, and pregnancy diet
✔ What to do if YOU have a food allergy and you're terrified of passing it to your baby

Risk categories covered:
→ No eczema / no family history: introduce at home around 6 months, no testing needed
→ Mild to moderate eczema: introduce early at 4–6 months, no testing needed, focus on skin care first
→ Severe eczema: consult your pediatrician and/or allergist before introducing; testing may come first

Episode 17 | Body Image Issues Start at Age 5 — What Parents Can Do Right Now

Here's something that stops parents in their tracks when I say it in clinic: body image concerns can show up as early as age 5. Not 13. Not even 10. Five.

That means by the time most of us think we need to start "the conversation," our kids have already been building a relationship with their bodies for years — shaped by what they hear, what they see, and what happens around food at home.

This episode isn't about fear. It's about getting ahead of it — with science, not pressure.

I'm a pediatrician and dietitian with 30 years of asking questions about how kids relate to food and their bodies. Body image is not a topic I can leave to chance, and I don't think you should either. The good news? The research on prevention is actually really hopeful. Small, consistent shifts in language and environment make a meaningful difference — and you don't need to be a therapist to make them.

In this episode we cover:

• When body image awareness actually starts (the research will surprise you)
• What puts kids at higher risk — and it's not what most people assume
• Specific language shifts to make at the table and in front of the mirror
• How to talk about bodies, food, and movement in ways that build respect, not fear
• The signs that tell you it's time to ask your pediatrician for a referral

Book Recommendation:

Episode 16 | Why Kids Have Big Feelings They Can't Explain: Understanding Interoception

Have you ever watched your child completely fall apart — hungry, overwhelmed, or just off — and they couldn't tell you why? They weren't being dramatic. Their nervous system literally didn't have the language yet.

That's interoception. And in this episode, I'm breaking it all the way down.

Interoception is your body's ability to sense what's happening inside — hunger, fullness, a racing heart, a tight chest, the need to move. It's the sixth sense nobody talks about, and it turns out it has everything to do with how our kids eat, regulate emotions, and eventually learn to trust their own bodies.

This one is close to my heart. As a pediatrician and dietitian, I see the downstream effects of poor interoceptive awareness every single week in clinic — and most of the time, no one has ever named it for these families.

In this episode we cover:

• What interoception actually is (and why it's not woo — it's neuroscience)
• How hunger and emotional signals share the same internal wiring
• Why kids who struggle to "calm down" often also struggle at the table
• The low-pressure ways you can support this at home without a therapy degree

→ If this episode landed for you, share it with another parent or save it for the next time your kid has a meltdown you can't explain. That moment is exactly when you'll want this.

Did you know your baby's veggie preferences start forming before their first bite of solid food? In this episode, Dr. Liz Daniels explores the fascinating science of flavor development, from pregnancy through the toddler years. Learn practical strategies to help your little one actually enjoy vegetables, understand the "beige stage," and discover why cultural approaches to baby feeding offer valuable lessons.

Key Topics Covered:

Early Flavor Development

• How babies detect flavors through amniotic fluid starting at 8 weeks
• The role of the olfactory system in taste preferences
• Fragrance compounds (vanilla, garlic, carrot, anise) detectable in utero
• Flavor transmission through breast milk (1-4 hours after maternal consumption)

Cultural Approaches to First Foods

The Science of Exposure

• 8-20 exposures needed for flavor acceptance
• Why variety matters more than hitting "100 foods under one"
• The critical texture window at 8-9 months

Practical Feeding Tips

• Herbs and spices are safe for babies
• Vegetables first vs. fruits first doesn't matter as much as frequency
• Different preparation methods count as valuable exposure

The Beige Stage (Neophobia)

• Typically starts 18-24 months, can last months to years
• Developmental autonomy and need for control
• Why kids reject previously loved foods
• Low-pressure strategies: invitation without expectation

Key Takeaways:
✓ Keep eating veggies during pregnancy and breastfeeding
✓ Offer the same veggie 8-20 times in different preparations
✓ Use family spices and seasonings from the start
✓ Don't give up during toddler rejection phases
✓ Focus on exposure and invitation, not expectation
✓ Your job: provide variety. Their job: decide what to eat

Newborn Poop 101: What’s Normal, When to Worry, and Why Baby Strains

Wondering if your newborn’s poop is normal? In this episode, I break down newborn and infant poop—what’s normal, what’s not, and when you actually need to worry.

As a pediatrician and registered dietitian, I walk you through what to expect in the first days and weeks of life, including the transition from meconium (black, sticky stool) to typical yellow stools, and how often newborns should poop. I explain why it’s common for stool patterns to change—and why growth, feeding, and overall symptoms matter more than any single diaper.

We also cover common parent concerns like:

• baby poop color (green, yellow, dark, pale)
• how often a newborn should poop
• baby straining to poop but stool is soft
• when poop frequency drops (even up to a week)
• mucus or blood in stool

I explain key red flags that may need medical attention, including poor weight gain and blood in the stool, and what those findings can mean.

You’ll also learn about infant dyschezia—a common developmental phase around one month where babies strain, cry, and turn red before passing a soft stool. I’ll explain why this happens and how to support your baby without over-intervening.

Plus, practical tips to make life easier (like preventing diaper blowouts and knowing when to size up).

If you’ve ever wondered, “Is this normal?” while staring at a diaper—this episode is for you.

In this foundational episode of Nutrition for the Early Years, I walk you through the stage before starting solids—because introducing food is about more than just the first bite.

If your baby is approaching the 4–6 month window, or you want to feel more confident before starting solids, this episode is for you. I break down what readiness actually looks like, how nutrition needs begin to change in infancy, and how I think through common questions like rice cereal, allergen introduction, water, cups, and baby-led weaning versus purées.

This is one of those episodes you may want to save and come back to.

In this episode, I cover:

• Developmental readiness for solids
• Why tummy time matters for feeding skills
• What the tongue extrusion reflex is and why it matters
• Iron needs in infants, especially for breastfed babies
• Why solids do not reliably help babies sleep
• When and how to start practicing with cups and water
• The role of cereal today
• Baby-led weaning versus purées—and why many families do both
• Early introduction of peanut and egg
• What the LEAP trial changed about infant feeding
• First food ideas and what a simple baby plate can look like

Key takeaways

Starting solids isn’t just about age—it’s about readiness, skill development, and understanding your baby’s changing nutritional needs.

In this episode, I explain why head and trunk control matter, why oral play and table exposure can start before true feeding, and why introducing solids too early doesn’t necessarily add benefit. I also share how I approach common infant feeding questions in real-life pediatric practice, including how I think about iron, allergen exposure, and balancing purées with baby-led weaning.

My goal is for you to walk away feeling more confident about:

• how to tell if your baby is ready
• what nutrients matter most in this stage
• how to begin allergen introduction thoughtfully
• how to keep the process simple, low-pressure, and developmentally supportive

A few reminders from this episode

• Babies should be sitting with good support and head control before starting solids in a meaningful way.
• Milk remains the nutritional cornerstone through the first year.
• Breastfed babies need more intentional iron support through complementary foods... for them, feeding before 1 is more than just fun!
• Solids are not a sleep solution.
• Water at this stage is for skill-building, not hydration replacement.
• Rice cereal isn’t “bad,” but grain variety matters.
• Baby-led weaning and purées can absolutely coexist.
• Early peanut and egg exposure reduce allergy risk in many infants.
• First foods don’t have to be complicated.
