Rough Serving Sizes for a Growing Appetite
In the first weeks after birth, a newborn’s stomach is roughly the size of a cherry — tiny, and filling fast. Within days it expands to the size of an apricot, then a large egg by two weeks. Knowing these physical limits helps you avoid both under- and over-feeding.
- 0-2 weeks: 1-2 oz per feeding, every 2-3 hours (8-12 times per day).
- 2-4 weeks: 2-3 oz per feeding, every 2-3 hours.
- 1-2 months: 3-4 oz per feeding, every 3-4 hours.
- 2-4 months: 4-5 oz per feeding, every 3-4 hours.
- 4-6 months: 5-6 oz per feeding, every 4-5 hours.
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.
From Puree to Finger Food at Each Stage
Introducing solids is a gradual negotiation, not a single event. Around six months, most babies can sit with support, track a spoon with their eyes, and “lose” the tongue-thrust reflex that pushes food back out. Those are the green lights. 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.
Reading Your Baby’s Hunger Cues, Not the Clock
Every pediatrician will tell you the same thing: watch the baby, not the clock. Crying is actually a late-stage hunger signal — by the time tears arrive, your baby has been requesting food for a while.
- Wet diapers: at least 6 wet diapers per day after the first few days.
- Steady weight gain: following their growth curve at pediatric visits.
- Active and alert: during waking hours, your baby seems engaged and responsive.
- Swallowing sounds: you can hear your baby swallowing during feedings.
- Satisfied after feeding: baby releases the breast or bottle and seems content.
If you have concerns about your baby's feeding or weight gain, always consult your pediatrician. Use our Weight Loss Calculator to track your own postpartum weight goals.
From Milk to Solids: A 4-Stage Timeline
Introducing solids is a months-long progression, not a single milestone. Each stage introduces new textures and serving expectations while breastmilk or formula remains the primary calorie source until around 12 months.
- Stage 1 — Liquid Only (0–5 months): Breastmilk or formula exclusively. No solids. Feed on demand every 2–4 hours. A newborn's stomach is roughly the size of a cherry at birth, expanding to an apricot by day 3.
- Stage 2 — Single-Ingredient Purées (6–7 months): Thin, smooth purées (iron-fortified cereal, mashed banana, pureed sweet potato). Start with 1–2 tablespoons once or twice a day alongside regular milk feeds. Watch for the tongue-thrust reflex to fade as a readiness sign.
- Stage 3 — Mashed & Soft Chunks (8–10 months): Thicker mashes and soft finger foods (scrambled egg, soft-cooked pasta, small cubes of avocado). Two to three small meals per day. Babies begin using a pincer grasp and self-feeding, which builds oral motor skills.
- Stage 4 — Family Foods (11–12 months): Chopped table foods and soft proteins (shredded chicken, diced fruit, small pieces of cheese). Three meals plus 1–2 snacks. Milk drops to 16–24 oz per day as food becomes the main nutrition source.
Every baby progresses at their own pace. If your baby pushes food out with their tongue or seems uninterested, wait a week and try again — it does not mean they are not ready, just that they need more time.
