Feeding Guidelines by Age

Feeding needs change rapidly during the first year of life. Newborns have tiny stomachs — about the size of a cherry at birth — and can only hold small amounts at a time. By 2 weeks, the stomach grows to about the size of a large egg, and continues expanding through infancy.

These are general guidelines. Every baby is different, and your pediatrician can provide personalized recommendations based on your baby's growth curve and individual needs.

Breastmilk vs Formula

Both breastmilk and formula provide complete nutrition for your baby, though they differ in composition. Breastmilk contains antibodies that help fight infections and adapts its nutritional content to your baby's needs. It is recommended as the exclusive food source for the first 6 months by the WHO.

Formula is designed to mimic the nutritional profile of breastmilk and is a safe, healthy alternative. Whether you choose breastmilk, formula, or a combination, the most important thing is that your baby is getting enough volume to support healthy growth and development.

Frequently Asked Questions

How often should a newborn eat?
Newborns typically eat every 2 to 3 hours, which means 8 to 12 feedings per day. Feeding on demand — whenever your baby shows hunger cues — is recommended over strict clock-based schedules in the first weeks.
How much formula per feeding?
Newborns start with 1 to 2 ounces per feeding, gradually increasing to 2 to 3 ounces by 2 weeks, 4 to 5 ounces by 2 months, and 6 to 8 ounces by 6 months. A general guideline is about 2.5 ounces per pound of body weight per day for formula-fed babies.
When to start solid foods?
Most pediatricians recommend introducing solid foods around 6 months of age. Signs of readiness include sitting up with support, showing interest in food, losing the tongue-thrust reflex, and being able to hold their head steady. Breastmilk or formula should remain the primary nutrition source until around 12 months.
How do I know if baby is hungry?
Early hunger cues include rooting (turning head and opening mouth), lip smacking, sucking on hands, and fussing. Crying is a late hunger cue. Watch for these earlier signs and respond promptly to establish healthy feeding patterns.
Can I overfeed a baby?
It is very difficult to overfeed a breastfed baby, as they naturally stop when full. Bottle-fed babies may occasionally be overfed if the bottle is pushed. Trust your baby's hunger and fullness cues, and do not force them to finish a bottle.
What is cluster feeding?
Cluster feeding is when a baby wants to feed very frequently — sometimes every 30 minutes to an hour — for several hours in a row. This is normal, especially during growth spurts (around 2-3 weeks, 6 weeks, and 3 months) and in the evening. It does not mean your milk supply is low.
