Quick Answers
The amount of formula a 6 week old drinks can vary, but here are some general guidelines:
- Most 6 week olds drink around 24-32 oz of formula per day

- Each feeding is usually 2-4 oz of formula

How Much Formula Do 6 Week Old Babies Need?
At 6 weeks old, most babies need around 24-32 oz of formula per day. However, this can vary quite a bit from baby to baby based on a number of factors:
- Weight: Heavier babies generally need more formula than smaller babies.
- Appetite: Some babies are heartier eaters and will consistently take more at each feeding.
- Time of day: Babies tend to eat more during daytime hours and less at night.
- Stage of development: Growth spurts can increase formula intake.
- Health conditions: Illnesses or reflux may affect how much a baby eats.
The best way to know if your 6 week old is getting enough formula is to follow their lead – watch for signs of hunger and fullness and adjust amounts accordingly. Pay attention to their diaper output and weight gain as well.
How Often Should a 6 Week Old Eat?
Most 6 week old babies need to eat every 2-3 hours, which typically works out to 8-12 feedings per day. Some key points on feeding frequency:
- Breastfed babies may eat a bit more frequently, such as every 1.5-2 hours.
- Bottle-fed babies can go a bit longer between feeds, around 2.5-4 hours.
- Overnight, feedings usually decrease to 1-2 times.
- Watch for early hunger cues and feed your baby whenever they seem hungry.
- Don’t go longer than 4 hours during the day without feeding.
If your baby is content and growing well, then their feeding schedule is working for them. Follow their lead rather than sticking to a rigid schedule. Babies will indicate when they’re hungry by cues like rooting, sucking, hands to mouth, etc.
How Many Ounces Should a 6 Week Old Eat Per Feeding?
At each feeding, most 6 week olds will take around 2-4 oz of formula. Some key points:
- Breastfed babies generally eat around 2-3 oz per feeding if given a bottle.
- Formula fed babies may take up to 4 oz or more if very hungry.
- Aim for the lower end of 2-3 oz at first.
- Let your baby’s cues determine if they need more at each feed.
- Only increase amounts if they seem hungry after finishing a bottle.
- Nighttime feeds are often smaller, around 2-3 oz.
To avoid overfeeding, start with 2-3 oz per feeding and let your baby determine if they need more. Watch for them becoming sleepy or disinterested versus showing hunger cues. Babies will naturally regulate their intake if fed responsively.
How to Know if Your 6 Week Old is Eating Enough
It’s common for parents to worry about whether their 6 week old is eating enough formula. Here are some signs that your baby is getting sufficient nutrition:
- Steady weight gain and growth along their curve.
- Producing the expected number of wet/dirty diapers.
- Seems satisfied and content after eating.
- Is generally happy, active and alert when awake.
- Sleeps well between feeds.
- Has good muscle tone and is reaching milestones.
On the other hand, the following may indicate underfeeding:
- Fussiness, irritability, or lethargy.
- Consistently acting hungry soon after feeds.
- Not producing enough wet/dirty diapers.
- Weight loss or lack of weight gain.
- Poor muscle tone or activity level.
If you are concerned your baby isn’t eating enough, contact their pediatrician – they can do an exam and help determine if formula adjustments are needed.
Tips for Feeding a 6 Week Old with Formula
Here are some helpful tips for feeding your 6 week old baby with formula:
- Follow safety guidelines: Properly sanitize bottles/nipples and follow instructions when preparing/storing formula.
- Choose an appropriate formula: Work with your pediatrician to find one that agrees with your baby.
- Hold your baby close: Formula feeding is still bonding time.
- Watch for fullness cues: Stop feeding when your baby seems disinterested or falls asleep.
- Burp during feeds: Take breaks every 1-2 oz to burp your baby.
- Respond to hunger cues: Feed your baby when they root, suck their hands, etc.
- Don’t overfeed: Start with smaller amounts and let your baby indicate if they want more.
The key is responding to your baby’s needs and hunger/fullness cues. With time, you’ll learn their schedule and how much they typically like to eat. Don’t hesitate to ask your pediatrician for help optimizing feedings.
Transitioning from Breastmilk to Formula
Some parents start supplementing with formula around 6 weeks or decide to switch completely at this stage. Here are some tips for transitioning from breastmilk to formula:
- Introduce bottles/formula gradually to help your baby get used to the taste and feel.
- Try offering a bottle after or in between breastfeedings at first.
- Mix together breastmilk and formula and adjust ratios slowly over a week or two.
- Substitute one feeding per day with formula, then increase to two, etc.
- Aim for a gradual transition over at least 2-4 weeks.
- Be patient – it may take some time for your baby to adapt.
Decreasing breastmilk supply too rapidly can lead to engorgement. You can use techniques like cool compresses, gentle massages in the shower, and over-the-counter pain relievers to find relief as needed.
Formula Feeding Schedule Sample for a 6 Week Old
Here is an example schedule showing how much formula a 6 week old may eat and how often:
| Time | Amount* |
|---|---|
| 7 AM | 3 oz |
| 9 AM | 3 oz |
| 12 PM | 4 oz |
| 3 PM | 4 oz |
| 6 PM | 3 oz |
| 9 PM | 3 oz |
| 12 AM | 2 oz |
| 3 AM | 2 oz |
| Total per day: | 24 oz |
*Amounts are estimates – let your baby’s hunger cues determine how much they need at each feeding.
Tips for Nighttime Feedings
Here are some tips to handle those middle-of-the-night feedings with your 6 week old:
- Take shifts with your partner so you can each get longer sleep stretches.
- Keep night lighting low and avoid stimulation.
- Change diaper first if needed then feed.
- Gently rock/sway while feeding to promote sleepiness.
- Don’t play or talk much; keep feedings boring.
- Burp then immediately put back down drowsy but awake.
- Introduce a pacifier for soothing between feeds.
- Sleep when baby sleeps – nap when you can.
Night feeds will gradually decrease as your baby begins sleeping for longer stretches. Hang in there – it does get better! Be sure to take care of yourself too.
Growth Spurts and Increased Appetite
It’s common for 6 week old babies to go through growth spurts and become extra hungry for a few days. Some signs include:
- Feeding more frequently/for longer periods.
- Waking up more often overnight.
- Appearing unsatisfied after feeding.
- Being fussier than usual.
- Increase in dirty diapers.
To handle growth spurts:
- Respond to hunger cues and allow baby to feed on demand.
- Offer an extra ounce if still showing hunger signs after finishing a bottle.
- Growth spurts usually only last 3-5 days.
- Remember this is a phase – your baby will go back to a more predictable routine.
Growth spurts are a sign your baby is developing well. Meet their increased demands for a few days until the spurt passes, then go back to a typical feeding routine. Contact your pediatrician if you have any concerns.
When to Talk to Your Pediatrician
In most cases, your 6 week old will let you know when they are hungry and full. But it’s a good idea to check in with your pediatrician if:
- Your baby is showing signs of dehydration – fewer wet diapers, dry mouth, etc.
- You are concerned your baby isn’t eating enough or regurgitating excessively.
- Your baby isn’t gaining weight appropriately.
- There are signs of stomach upset with feedings – pain, gassiness, spitting up, etc.
- You suspect a food allergy – rash, blood in stool, vomiting, etc.
Your pediatrician can help evaluate if there is an underlying issue affecting your baby’s feedings or growth. Don’t hesitate to reach out with any concerns.
Conclusion
How much a 6 week old eats can vary quite a bit from baby to baby. For formula fed infants, aim for around 24-32 oz total per day, spread out over 8-12 feeds. Offer 2-4 oz per feeding and let your baby’s cues determine if they need more. With responsive, attentive feeding and guidance from your pediatrician as needed, you can ensure your baby is getting all the nutrition they need during this important developmental phase.
