Pregnancy
Phase 1
Phase 2
Phase 3
Pregnancy

During pregnancy

Pre-birth
  • Brain forms billions of early connections

  • Sterile gut develops, no bacteria yet

  • Early metabolism shaped by mom's diet

  • Bones grow quickly and begin to mineralize

Phase 1

Welcome to the world

0-4 months
  • Brain grows fast, reaching half its adult size

  • First gut microbes start building immune strength

  • Baby’s metabolism adjusts and starts forming patterns

  • Bones grow quickly, absorbing calcium to build strength

Phase 2

Transition

4-8 months
  • Brain sharpens as memory and attention develop

  • First solids help grow a healthy gut microbiome

  • Metabolism begins using fats & nutrients more efficiently

  • Growth spurt kicks in, bones and body stretch fast

Phase 3

Building lasting habits

8-12 months
  • Brain nears 80% of adult size, learning happens fast

  • Immune system strengthens as gut adapts to more foods

  • Food preferences and appetite patterns start to form

  • Muscles and bones prep baby for standing & walking

Gut & Immune Health

How your baby's gut and immune system develop together

Immune system

Gut microbiome

Digestive system

Key nutrients

What you can do

Why it matters

Phase 1

0-4 months

Immune system

Bacteria from milk train your baby's immune system to recognize helpful bacteria.

Gut microbiome

Microbiome at 0-4 months

Digestive system

Your baby's gut starts growing healthy bacteria from milk to support digestion.

Key nutrients

HMOsMFGMIgAProbioticsLactoferrinVit D

What you can do

Choose formulas with gut friendly nutrients & multiple HMO strains. Avoid too much iron which can disrupt early microbiome.

Why it matters

A healthy gut early on builds stronger immunity & can help prevent digestive issues.

Phase 2

4-8 months

Immune system

New foods introduce new bacteria, helping your baby's immune system distinguish good bacteria from harmful ones.

Gut microbiome

Microbiome at 4-8 months

Digestive system

As your baby eats solids, their gut bacteria become more diverse, helping digestion adapt and improve nutrient absorption.

Key nutrients

HMOsProbioticsMFGMAllergensIg ALactoferrin

What you can do

Gently introduce allergens at right time based on your baby's risk profile, alongside gut-supportive foods.

Why it matters

Introducing allergens at the right time can reduce food allergies by up to 80%.

Phase 3

8-12 months

Immune system

A diverse diet helps your baby's immune system mature and build stronger defenses.

Gut microbiome

Microbiome at 8-12 months

Digestive system

A richer diet further diversifies bacteria, helping your baby learn to digest a variety of textures and flavors comfortably.

Key nutrients

Diverse fibreProbioticsHMOsPrebiotics (GOS/FOS)Allergens

What you can do

Introduce textured, fiber-rich foods and safe fermented foods. Avoid unpasteurized foods due to harmful bacteria.

Why it matters

A healthy gut at this stage sets the foundation for lifelong immune & gut health.

Foundational Growth

How your baby builds strong bones and muscles in the first year

Bone growth

Muscle growth

Key nutrients

What you can do

Why it matters

Phase 1

0-4 months

Baby growth at 0-4 months

Bone growth

Your baby's bones are stretching and quickly absorbing nutrients like calcium, laying a strong foundation for growth.

Muscle growth

Tiny movements (like grabbing your finger) are helping early muscles wake up and get ready for bigger movements.

Key nutrients

CalciumVit DPhosphorusHigh quality proteinsMagnesiumSN-2 Palmitate

What you can do

Breastfeeding? Eat calcium-rich foods and supplement vitamin D. Formula-feeding? Pick formulas without palm olein for better calcium absorption.

Why it matters

Good early nutrition helps your baby reach next milestones more confidently.

Phase 2

4-8 months

Baby growth at 4-8 months

Bone growth

Your baby is entering a growth spurt and its bones are hardening to handle more movements like sitting up and crawling.

Muscle growth

All that wiggling and rolling helps build strong, healthy muscles.

Key nutrients

CalciumIronVit DGood proteinPhosphorusAmino acids

What you can do

Pair iron-rich foods (meats, cereals) with vitamin C-rich fruits to boost absorption. Include proteins like eggs to support muscles for crawling.

Why it matters

Strong early muscles can impact balance, coordination and athletic ability.

Phase 3

8-12 months

Baby growth at 8-12 months

Bone growth

Bones become stronger and denser, supporting standing and early steps.

Muscle growth

Legs and core muscles work hard to improve balance and coordination.

Key nutrients

CalciumIronGood proteinVit DPhosphorusAmino acidsHealthy fats (omega-3, MCT)

What you can do

Offer healthy fats (avocado, fish) and proteins (beans, eggs, meats) to build strong muscles and coordination for early walking.

Why it matters

First-year growth trajectory can influence adult height potential.
