As a new parent, watching your baby grow is one of the most exciting things! You may find yourself wondering about your baby’s weight gain and what’s “normal” in those early days. Weight gain is an important part of newborn health, but it can look a little different than many parents expect. Let’s talk about what’s typical for newborn weight gain and what to keep an eye on.
The First Few Days: Weight Loss Is Normal
One thing that surprises many new parents is that newborns typically lose weight in their first few days after birth. Most babies lose about 5–10% of their birth weight within the first week. This is completely normal! Babies are adjusting to life outside the womb, and their bodies are getting used to feeding and digesting. As they lose some of the fluids they were born with, you might notice their weight drop a little bit.
By the time your baby is 10–14 days old, they’ll usually start to regain any weight they lost and may even exceed their birth weight. This is often when parents can start seeing that steady, healthy weight gain we love to track!
What’s Typical for Weight Gain After the First Weeks?
Once they’re past those initial days, babies usually start gaining weight more predictably. On average, newborns gain about:
- 5–7 ounces per week for the first month.
- 1–2 pounds per month for the first six months.
Of course, each baby is unique, and growth rates can vary. Some babies are naturally more petite, while others are bigger right from the start. That’s why pediatricians look at the overall trend in weight gain rather than focusing too much on exact numbers at each visit.
How Feeding Affects Weight Gain
If you’re breastfeeding, your baby might gain weight a little differently than a formula-fed baby. Breastfed babies sometimes gain weight a little slower at first, especially while both you and your baby are getting the hang of breastfeeding. This is usually perfectly healthy and normal.
Both breastfed and formula-fed babies should start showing consistent weight gain as feeding becomes more established. If your baby is getting enough milk or formula, you’ll see signs of a satisfied, well-fed little one.
Signs Your Baby Is Getting Enough
Wondering if your baby’s weight gain is on track? Here are a few signs that your baby is feeding well and gaining healthily:
- Plenty of wet and dirty diapers: Babies should have at least 6–8 wet diapers a day after the first week.
- Alertness and contentment: A well-fed baby is generally content after feeding and alert when they’re awake.
- Healthy, steady weight gain: Your pediatrician will track your baby’s weight gain over time, so regular check-ups are a great way to monitor their progress.
If your baby is showing these signs, they’re likely doing great!
When to Reach Out to Your Pediatrician
If you’re ever worried about your baby’s weight gain, reach out to your pediatrician. While weight gain varies, there are some situations when it’s a good idea to check in:
- If your baby hasn’t regained their birth weight by 2 weeks old.
- If they seem constantly fussy, especially after feedings.
- If they’re not having enough wet or dirty diapers each day.
Pediatricians are used to answering questions about newborn weight gain, so never hesitate to ask for advice or support.
Tips for Supporting Your Baby’s Weight Gain
Whether you’re breastfeeding, formula feeding, or doing a combination, there are a few things you can do to help ensure your baby’s growth stays on track:
- Frequent feedings: In the first few weeks, newborns usually eat about every 2–3 hours. Offering feeds regularly ensures they get the nutrition they need.
- Skin-to-skin contact: This isn’t just great for bonding—it can also help stimulate feeding cues and support breastfeeding.
- Feeding on demand: Let your baby guide feeding times whenever possible. Newborns are good at letting you know when they’re hungry!
Trust the Process: Embracing Your Baby’s Unique Growth Journey
It’s natural to feel eager to see your baby’s weight steadily increase, but remember that every baby grows at their own pace. The most important thing is the overall trend of steady growth, not the specific number on any given day. Your baby’s pediatrician will be there to help you track their progress and answer any questions along the way.
Remember, you’re doing an incredible job caring for your baby! With lots of love, regular feeds, and those important check-ups, your baby’s growth will take its own healthy, wonderful path. Enjoy watching them grow—each ounce is a milestone worth celebrating!
