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.

My first food philosophy

Simple, single ingredients that are super squishable or oversized.

Mentioned in this episode

• The LEAP study on early peanut introduction
• Research on baby-led weaning and choking risk
• Infant CPR and choking resources
• Guidance on readiness, feeding skills, and early allergen exposure

Listener note

Every baby is different. My hope is that this episode helps you feel informed and empowered as you start solids. Use this information as a springboard for a conversation with your pediatrician, especially if your baby was born pre

What do you do when your kid refuses milk?

Milk is one of the easiest ways to deliver calcium, protein, and vitamin D to growing kids. But kids are kids—and sometimes they just don’t like it.

In this episode, I’m walking you through exactly how I approach this situation in clinic with families. Because the goal isn’t forcing milk.

The goal is meeting your child where they are while still covering the nutrition they need to grow well.

I share the story of a toddler from my practice who absolutely refused milk after turning one—and how we worked through it step by step until his nutrition needs were fully covered without daily mealtime battles.

If your child refuses milk, or you’re worried about calcium or vitamin D intake, this episode will give you a simple playbook so you can stop overthinking it.

• Why milk is such an efficient nutrition source for toddlers
• How much calcium and vitamin D kids actually need
• When chocolate milk or flavored milk can actually be a helpful bridge
• One toddler food I love that can provide 400+ mg of calcium
• What to do when kids refuse dairy entirely
• Why vitamin D can be hard to get from food alone
• When I start recommending supplements

1. Strategically flavoring milk to bridge toward plain milk
2. Using yogurt and fermented dairy options
3. Looking beyond dairy for calcium (like tofu and beans)
4. Building calcium into foods toddlers already enjoy
5. Supporting vitamin D when food sources fall short

Sometimes kids refuse milk for a season. That doesn’t mean their nutrition is doomed.

With the right approach, we can still support strong bones, healthy growth, and balanced nutrition—without turning every meal into a negotiation.
