What it is
A growth spurt is a short stretch, usually two to three days, when the baby feeds far more than usual and seems suddenly hungry all the time. Mothers search '3 week growth spurt' and '6 week' because those are the classic ones. The baby may sleep more, or less, and be fussier. The extra feeding tells your body to make more milk, and within a few days it does.
What's typical
Common windows: around 7 to 10 days, 2 to 3 weeks, 4 to 6 weeks, 3 months, and 6 months. Each lasts two to four days. The baby may feed every hour and a half, and breasts feel softer than usual. Diaper counts should stay normal. Weight often jumps right after. Not every baby follows the schedule. Formula-fed babies have spurts too.
What's known
La Leche League and the Australian Breastfeeding Association describe growth spurts as normal and short-lived. Research shows infant growth happens in bursts, not a smooth line. The timing is approximate.
What helps
- Feed on cue. Two or three days of extra feeds is how supply rises to meet the new demand.
- Clear the calendar. Couch, snacks, water, help with the other kids.
- Count diapers if you are worried. Normal output means it is a spurt, not a supply drop.
When to call someone
- Todaywet diapers drop below six a day, or the baby is hard to wake.
- At your next visit'spurts' that last more than a week, or weight gain that has stalled.
