The first 1,000 days: a science-based “early years” guide.

From pregnancy to the second birthday, a child’s brain develops faster than at any other time. This guide turns the WHO and UNICEF Nurturing Care framework into a Turkey-adapted, fully cited and actionable structure for families. The goal is not isolated tips but the whole: health, nutrition, care, safety and learning.

The 5 components of nurturing care

WHO · UNICEF

The Nurturing Care framework (WHO, UNICEF and the World Bank) addresses the early years across five interconnected domains. This is the spine of this guide.

Health

Routine health monitoring, vaccines and timely care during illness. In Turkey, vaccines follow the Ministry of Health Expanded Programme on Immunization.

Nutrition

Exclusive breastfeeding for the first 6 months, then safe complementary feeding and responsive feeding. Growth is tracked with WHO 2006 standards and Neyzi 2008 for Turkey.

Responsive caregiving

Reading and responding to a baby’s cues consistently and warmly. Attachment, talking and eye contact build the foundation of brain development.

Safety and security

Safe sleep (on the back, separate cot), injury prevention (falls, drowning, poisoning, burns) and a proper car seat. A safe environment lowers stress.

Early learning

Play, talking and shared books support developmental milestones. Interaction matters more than expensive toys.

How we differ from tracker apps

UNICEF’s free apps (Bebbo / Merhaba Bebek) are strong at tracking growth, vaccines and milestones; we recommend and cite them. Child Growth adds a clinical-scientific layer on top of that foundation:

  • Adult height prediction: not one percentile, but five methods read together.
  • AI bone age + Greulich-Pyle second-opinion comparison.
  • Child-athlete development, maturation and bio-banding.
  • Clinician, coach and federation workflows + PDF reports.

Frequently asked questions

Why are the first 1,000 days so important?

From pregnancy to the second birthday the brain develops faster than at any other time. Nutrition, loving care, safety and stimulation in these years build the long-term foundation for health and learning.

Which source should I follow for the vaccine schedule?

In Turkey, vaccines follow the Ministry of Health Expanded Programme on Immunization. International sources give context, but the applied schedule and doses come from the Ministry of Health and your pediatrician.

When should complementary feeding (weaning) start?

WHO and UNICEF recommend exclusive breastfeeding for the first 6 months, then introducing safe complementary foods while continuing breastfeeding. Ask your pediatrician about timing and method.

Does this page replace a tracker app?

No. We recommend free tracker apps such as UNICEF’s Bebbo / Merhaba Bebek. Child Growth adds a clinical-scientific layer on top — adult height prediction, bone age and child-athlete development.
