All You Need to Know About Formula Feeding Your Baby

Formula feeding can be a boon for most mothers who are working women as it enables them to not rely on breastfeeding. Moreover, it can be very important in cases where the mother is not able to produce enough milk to feed the baby, or in cases where the milk is not suitable due to some disease in the mother.

Baby formulas can also be used to supplement breast-feeding and be a practical option for a lot of mothers due to circumstances. While the reasons for formula feeding are varied, most mothers generally have a number of questions about formula feeding.

The first and foremost question refers to the pros and cons of formula feeding vs. breastfeeding.


  • If you are going back to work after having a baby, this can help to divide the responsibilities of the baby with your partner or any caregiver for the baby.
  • If you are feeding the baby a baby formula, this is the best way for your partner to bond with the baby as they can engage in the precious moment of feeding the infant, which is not really achievable if you are breastfeeding.
  • If you are in a public situation, feeding your baby breast milk is often frowned upon and can be a bit of an embarrassment for the mother. Formula feeding your baby can be a better idea in these situations.
  • It can be reassuring to know how much your baby is feeding.


  • Though baby formulas claim to be complete in their nutritional value and manufacturers are constantly competing to make their formulas resemble breast milk, there can be no doubt that it is an inferior product as compared to breast milk. Apart from its nutritional value, breast milk has antibodies and antibacterial properties which boosts the baby’s immune system.
  • Baby formula can be expensive, as you not only have to buy the formula, but also the bottles, the teats as well as the sterilising equipment.
  • It’s much more time consuming.
  • The baby’s irregular feeding patterns can be a problem for people who are bottle-feeding as they will need time to prepare the formula.

With the pros and cons in mind, the next important question is the actual procedure on how to safely feed your baby any type of formula and the way to prepare the formula for feeding it to your baby.

While breast milk is the only type of food that your baby needs, if you are for any reason, unable to feed your baby breast milk, you can feed your baby any type of store bought baby formula by carefully following the instructions given on the pack.

You can give your baby cow milk based formula unless otherwise specified by your healthcare provider.

Types of Instant Formula

There are 3 kinds of formula that you can readily find at a store- ready-to-feed formula, concentrated liquid form, and powdered formula of which powdered formula is not sterile and must be prepared as instructions on the pack.

What formula should you feed your baby?

If your baby is born healthy and at full term, that is at 37 weeks or more, you can give your baby any type of formula. If your baby is a ‘high risk’ baby, you should prefer ready to feed and concentrate formulas over powder, however, it is okay to feed powder if you can’t find these.

A baby qualifies as a ‘high risk’ if-

  • The baby was born before 37 weeks and is less than 2 months old.
  • If the baby was born with a weight less than 2,500 gms and is less than 2 months old.
  • Your baby has a weak immune system and is likely to get sick often.

How to Clean and Sterilize Your Equipment for Making Baby Formula

With the safe way to feed your baby any type of baby formula in mind, here are some other commonly asked questions that you may have about formula feeding-

How often should you feed your baby?

You should feed your baby whenever he/she demands for it or seems to be hungry. Most newborns need to be formula-fed every 2-3 hours and as they grow older and are capable of retaining more milk, they usually feed every 3-4 hours.

If your baby is very young and/or having problems in gaining weight, you need to feed it every 2-3 hours even if it means waking him/her up from sleep.

How should you know that your baby is hungry?

Some of the signs that indicate that your baby is hungry include-

  • Moving head from side to side
  • Opening mouth
  • Sticking out tongue
  • Sucking hands/ fingers or fists
  • Puckering lips in a sucking motion
  • Nuzzling against mother’s breasts
  • Rooting reflex or moving the mouth towards something stroking the cheeks or lips.
  • Crying- crying is a late stage of hunger and you should be feeding your baby before it reaches the stage of crying from hunger as the baby may become too restless to be calmed down easily.

However, babies cry for a variety of reasons apart from hunger. If your baby is crying, you can present the nipple to see if it wants to feed if it doesn’t, do not force feed your baby. Your baby may need to be cuddled, changed or may just be over-stimulated, too hot/too cold or even just simply bored.

If the baby is crying just an hour after crying, chances are, something else is causing distress.

How Much should My Baby Drink?

For the first few weeks, 6-9 ounces of formula is enough, after which you will get accustomed to your baby’s feeding patterns and can make more at a time.

  • An average newborn drinks around 1.5-3 ounces of formula every 2-3 hours and this amount increases as the baby grows older.
  • At about 2 months of age, the baby needs about 4-5 ounces of formula every feeding spaced out at around 3-4 hours.
  • At 4 months, the baby needs about 4-6ounces depending on the frequency of feeding and the size of the baby.
  • By 6 months, the baby needs 6-8 ounces every 4-5 hours depending on the inclusion of baby food to the diet.

Is There Anything to Worry About If My Baby Seems to be Hungrier Than Usual?

As the baby grows older, it will need more formula and will be able to retain it for longer, however, there are periods at which the baby will seem to be hungrier than usual and these periods generally coincide with certain growth spurts that occur usually around the ages of-

  • 7-14 day old
  • 3-6 weeks
  • 4 month
  • 6 month

During these stages, increase the amount of food and feed every time the baby demands food.

Is Your Baby Eating Enough?

While babies all have different rates of growth, often as a parent, you are likely to wonder if your baby is getting the proper nutrients for growth. Regular check-ups can monitor your baby’s weight, but there are other ways to determine if the baby is feeding enough.

Your baby’s diapers are a good indication as you will be changing around 6-8 soiled diapers every day initially, with newborn poop being thick and tarry in the beginning and developing into a yellowish green colour as they grow.

Formula fed babies have firmer and less seed-like stools than breast-fed babies. The urine of your baby should be pale or clear. Contact the doctor if you see orange crystals or are concerned about any lack of nutrition in your baby.
