To prepare Bobbie formula, add one unpacked, level scoop of powder for every 2 fl. oz. of warm water. Always add water first, then powder, and shake to mix thoroughly.

Tap Water

✅ Usually perfectly fine

✅ Convenient and economical

❓ Ask your pediatrician or local health department if you have concerns

Bottled Water

✅ Can be a good backup option

❓ Check expiration dates (yes, water can expire!)

⚠️ Not all bottled waters are created equal—avoid mineral or sparkling varieties

Distilled or Purified Water

✅ Both are completely fine to use

✅ Ready to use without boiling

✅ Good option when traveling or if tap water quality is questionable

The Temperature Sweet Spot

For optimal formula reconstitution, warm water to 100°F (38°C). This temperature helps the formula dissolve properly and ensures all those nutrients mix perfectly. Not too hot, not too cold—just right for baby's belly and the formula's chemistry.

The Golden Rule

ALWAYS follow the mixing instructions on the formula container.

Formula is scientifically designed with specific water-to-powder ratios.

Check out this article for more details about choosing the best water for your baby.

You can store a freshly prepared and untouched bottle of Bobbie formula at room temperature for up to 2 hours or in the refrigerator for up to 24 hours. Once feeding from the bottle has begun, discard the bottle after 1 hour. Don’t refrigerate leftover formula to save it for later.

Bobbie baby formula that has been prepared but not yet offered to your baby can last in the refrigerator for up to 24 hours. You can prepare a batch of formula in bulk, up to a day's worth, and keep it in the fridge until you need it! Any powder formula that you have prepared with water should be kept in the fridge, in a sealed container, such as a formula mixing pitcher or in individual bottles, until ready to serve.

Unfortunately no, once a bottle of formula has been heated it must be used within 1 hour. If parents prefer to offer warm bottles, they should be heated immediately before each feeding using a bottle warmer or a mug of hot water– never the microwave! Given the shorter window for how long formula stays good after heating, many parents choose to offer their baby room temperature formula or even chilled formula straight from the fridge. That’s right! You do not need to heat your baby’s formula bottle before serving!

The amount of formula your baby needs will likely vary as they grow. The American Academy of Pediatrics recommends that infants consume approximately 24-32 ounces of formula or breastmilk per day during their first year.

If you're mostly breastfeeding and/or combo feeding your baby, your Bobbie journey will look different from what we've listed above. Breastmilk intake can vary substantially from formula intake due to the changing nutrient content of breastmilk as a baby ages. We recommend taking our Formulator Quiz to ensure you're selecting the Bobbie bundle size that's just right for your family.

Bobbie Organic Whole Milk Infant Formula is a great everyday starting point for most babies. If your baby is dealing with excessive fussiness, gas, or crying, Bobbie Gentle Formula is designed with partially broken down proteins for easy digestion. You can always switch as your baby’s needs change. Not sure where to start? Take our Find My Baby Formula Quiz.

Every baby is different, but we recommend a full transition to Bobbie from day 1! We don’t recommend combining formulas since it could complicate what must go through your baby's sensitive digestive system! Here are some best practices for transitioning:

• Introduce a new formula in the morning so you can keep an eye on your baby throughout the day
• Remember that it can take your baby around a week to fully adapt to a new formula (in the meantime, you may notice changes to poop schedule, color or texture, increased gas, grunts, or changes in spit-up—this is common and expected!)
• Chat with your pediatrician before making the switch to ensure a smooth transition, or if you’re unsure whether your baby is tolerating their new formula!

Here’s a quick video from our team on switching your baby to Bobbie. Also, check out this article on transitioning from our blog, Milk Drunk!

A baby’s eating habits are as unique as any of their other features! The frequencies provided on this feeding guide are just that—a guide. If you’re concerned that your baby is eating too frequently or not frequently enough, please consult with your pediatrician. A variety of feeding frequencies can be normal and may not be cause for concern, so long as your baby is gaining weight appropriately and is meeting developmental milestones as expected.

Yes, this is very normal. Feeding charts are general guidelines, but every baby is different. While the American Academy of Pediatrics recommends infants consume roughly 24-32 ounces of formula or breast milk per day during the first year, how much an infant eats at each feeding isn’t always consistent. As long as your baby is gaining weight and producing regular wet diapers, variations in intake are expected. If you’re concerned about your baby’s growth, please consult with their pediatrician.

Bobbie Organic baby formula is made without synthetic pesticides, GMOs, or certain additives, which many parents prefer. Bobbie organic formulas are designed to offer clean, high-quality nutrition while meeting all FDA requirements.

Overfeeding is more likely to happen with bottle-fed babies than breastfed babies. Signs of overfeeding may include:

• Increased spit-up or vomiting
• Gas or other digestive discomfort
• Weight gain that accelerates more quickly than expected, based on developmental percentile charts

If you’re concerned that you may be overfeeding your baby, please consult with your child’s doctor to discuss feeding volume, frequency, and symptoms you may be noticing.

Infants need to eat frequently—not only because they have a smaller stomach capacity, but also because they are growing at a more rapid rate than they will at any other time in their lives! Babies need adequate calories, fat, and other nutrients to grow. Signs of underfeeding may include:

• Lethargy or excessive sleepiness
• Dehydration (dry mouth, sunken in fontanelle aka ‘soft spot’ in the skull
• Slower than expected weight gain
• Fewer than expected daily wet and/or dirty diapers

If you’re worried that your baby may not be eating enough, please discuss with your child’s doctor to evaluate feeding volume and frequency, and eliminate possible medical conditions that can contribute to slow weight gain.
