Formula Feeding Your Baby

Two people sit on a bed with pillows. One holds a newborn wrapped in a white blanket, while the other leans in and smiles at the baby.

Deciding how to feed your baby may come with a lot of questions. You may feel overwhelmed with the amount of information there is. If you are trying to decide and want more information on breastfeeding/chestfeeding see our article, Breastfeeding/Chestfeeding – Good for Baby, Good for You.

If formula feeding is part of your plan for your healthy, full-term baby, this information is for you. Ask your health-care provider about what type of formula is best if your baby: 

  • is premature 
  • is ill 
  • had a low birth weight 
  • has special needs

How to choose an infant formula 

  • There are many types and brands of formula on the market. Choose what works best for your situation unless your health care provider says your baby needs a special formula. Do not choose a formula based on advertising or the brand they gave you in the hospital. 
  • All formulas must meet safety standards set by Health Canada. The law requires that all brands of regular formula have the same basic ingredients. 
  • For most babies, a cow’s milk-based, store-bought infant formula with iron is best. Always check the label for the type of infant formula you are buying for your baby. 
  • Formula with prebiotics, probiotics or DHA and ARA fats added are available. However, the research is mixed about whether these types of formulas are beneficial for all babies. 
  • Organic formula is not necessary. Parents may choose it for personal reasons. 
  • Formula with “partially broken down” proteins is not needed by most infants but may be recommended by a health-care provider for some medical conditions. 
  • When buying formula, check the expiry date on the package. Do not use formula that is expired. 
  • Never buy formula if the container is damaged, dented, unlabelled or bulging. 
  • Formula-fed babies need to stay on infant formula until they are nine to 12 months of age. “Follow-up” formula is not needed.

  • homemade formula 
  • cow’s milk or goat’s milk 
  • plant-based beverages made from almonds, cashews, soy, rice or other plants

There are three types of infant formula 

  • Ready-to-use – It really is ready to use. You do not need to add anything to it. This type is generally the most expensive. 
  • Concentrated liquid – You need to add sterile water according to the directions on the package. This type is also more expensive. 
  • Powder – This is the least expensive type of formula. Unlike the others, powdered formula is not sterile. It is not recommended for babies who:
    • are born premature (less than 37 weeks gestation) and are under two months of age 
    • are born with a low birth weight (under 2.5 kilograms) and are under two months of age 
    • have a weakened immune system 

If you’re unsure, talk to your health-care provider before giving powdered formula to your baby.

More things you need to know about formula feeding 

Feeding your baby is more than providing nourishment. It’s also a time to learn about your baby and connect with each other. This helps your baby grow and develop. Skin-to-skin contact during feeding has many benefits, including calming your baby and helping them feel safe and secure.
