Basics of Newborn Nutrition in the First Month of Life

Introduction: Why Nutrition in the First Month Is Vital

Nutrition for a newborn in the first 30 days lays the foundation for their health and development. During this period, the infant’s body adapts to life outside the womb, and the immune system is just beginning to form. The primary food source is breast milk or adapted formula, providing all the essential macro- and micronutrients. It is important to follow a feeding schedule and avoid introducing solid foods, which can negatively affect the baby’s digestion and immunity.

Main Sources of Nutrition: Breast Milk and Formulas

Breast milk remains the best choice for the first month of life. It contains antibodies, enzymes, and essential fatty acids that support brain development and immunity. The World Health Organization recommends exclusive breastfeeding for the first 6 months—this is especially relevant in 2026 considering the latest research.

Adapted Formulas: When and Which Ones?

If breastfeeding is not possible, adapted milk formulas are used. Modern brands like Nutrilon and NAN offer formulas with an optimal balance of proteins, fats, and carbohydrates, as well as added vitamins D and E. The average price for such formulas in Moscow in 2026 is around 1200–1800 rubles per 400 grams, providing the baby with complete nutrition.

• Nutrilon Premium — with prebiotics to support digestion
• NAN Hypoallergenic — for children at risk of allergies
• Similac with DHA and ARA — for brain and vision development

Feeding Schedule: How Often and How Much?

In the first month, a newborn usually feeds 8–12 times a day, which corresponds to feeding every 2–3 hours. The volume per feeding grows from 30–60 ml in the first days to 90–120 ml by the end of the month. It’s important to follow the baby’s cues and avoid overfeeding or long intervals without feeding.

Tips for Organizing Feeding

• Feed on demand — without a strict timetable
• Watch for hunger signs: sucking motions, restlessness
• Avoid supplementing with water or juices without a doctor’s recommendation

Hydration and Additional Nutrition

In the first month, breast milk or formula provides adequate hydration. Additional water is unnecessary, as excess fluid can disrupt the water-electrolyte balance. Introducing solid foods is strictly not recommended before 4–6 months according to modern pediatric standards.

In regions with hot climates, such as Moscow in summer 2026, it is important to monitor signs of dehydration, but additional water should only be given under medical advice.

Strengthening Immunity Through Nutrition

Breast milk contains immunoglobulins and lactose that stimulate the growth of beneficial gut flora. This promotes immune system development and protection against infections. For babies on formula, modern products are enriched with prebiotics and vitamins to support immunity.

Vitamins and Micronutrients

A doctor may recommend additional vitamin D supplementation at a dose of 400 IU per day, especially in northern regions of Russia where sunlight exposure is low in winter and spring. This helps prevent rickets and supports bone development.

• 8-12 times feeding frequency per day for a newborn
• 400 IU daily vitamin D dose for infants
• 1200-1800 ₽ average price of adapted formulas in Moscow
