How much weight should my newborn gain per week?
1 min read
Most newborns gain about 2/3 of an ounce (20–30 grams) per day, which works out to roughly 4 to 7 ounces per week once they're back to birth weight.
Most babies lose about a tenth of their birth weight in the first five days, then regain it by around day ten. After that, most babies grow fast, especially during growth spurts around 7 to 10 days and again between 3 and 6 weeks. By one month, the average baby weighs about ten pounds (4.5 kg) and has grown 1 1/2 to 2 inches.
Keep in mind these are averages, not targets; a healthy baby can sit a bit above or below them. The clearest way to know yours is on track is the weight check at each well-child visit, where your pediatrician follows the trend on a growth chart.
What you can do
- Feed on demand, watching for hunger cues rather than the clock
- Count wet and dirty diapers as a sign of enough intake
- Keep all well-baby checkups so growth is tracked over time
- Don't panic over day-to-day changes; trends matter more than single numbers
Based on AAP guidance. Always consult your pediatrician for personalized advice.
