My sister just gave birth today, & while shes trying to breastfeed her baby it brought back so many memories. I remember how overwhelming those first days felt constantly wondering “Is my baby eating enough?”
What most of us aren’t told is the actual size of a newborn’s stomach👀
Day 1: size of a blackberry
➡️5–7 mL (1–1.5 tsp)
• Colostrum is perfectly designed for this tiny tummy
Day 2: size of a strawberry
➡️10–15 mL (2–3 tsp)
• Frequent feeding is normal and expected
Day 3: size of an egg
➡️¾–1 oz (22–30 mL)
Day 4–5: size of a lime
➡️1.5–2 oz (45–60 mL)
By 3–4 weeks: size of a tomato
➡️3–4 oz (90–120 mL)
In the early days, babies are not meant to take large volumes. This is why cluster feeding, frequent nursing, or small pump outputs are biologically normal not signs of low milk supply.
As your baby grows, their stomach expands, and your milk supply increases gradually in response to frequent, effective milk removal.
Your body isn’t behind—it’s following biology 🤍
✨ Important reminder⬇️
Small feeds + frequent feeds = normal newborn behavior.
