Finding the right baby formula for your infant can a while to figure out. The formula that you start with may not be the one that you use for a long time – be it for cost, allergies, or nutrition, you might want to switch formulas. In this helpful guide, we’ll show you how to change baby formulas and keep your baby happy. With this guide (and your doctor’s advice), you’ll be able to switch formulas without getting your baby fussy.
- Consider the protein type
Most formulas either contain cow milk, goat milk, or soy-based milk. Each milk type differs in protein. If your baby is lactose intolerant, your doctor might advise you to switch to goat milk as it has lower levels of lactose compared to cow’s milk. If the new formula contains the same type of protein, you can make the switch immediately. In case the protein is different, you might want to make the switch more gradually.
Another factor to consider is whether the milk is partially or fully hydrolyzed. If the new formula also contains the same level of hydrolyzed protein, you can make the switch instantly. Otherwise, it is recommended to take things slow (follow Method 2).
- Read the label for the additives
Formulas are usually fortified with additives to supplement your infant’s nutritional needs. Based on your baby’s diet and requirements, your doctor might recommend formulas with additional vitamins, iron, or DHA.
Read the label to check the percentage of additives in your formula. If the new formula has the same nutrients as the old one, you can make the switch instantly. If it doesn’t, it is recommended to gradually switch to the new formula.
- Learn how to switch
There are two ways to switch your baby’s formula. Method 1 is instant, while Method 2 is more gradual.
Method 1:
If your baby is allergic to the old formula, or if the new formula has the same proteins and additives as the old one, you can switch formulas immediately. Feed your baby the new formula without mixing the old one in. In case your baby fusses about the new formula, try again when it is really hungry.
Method 2:
In case your new formula has different proteins or additives, it is recommended to make the switch gradually so that your baby is eased into it. Here’s a day-by-day breakdown:
- Day 1: 100% old formula + 0% new formula
- Day 2: 75% old formula + 25% new formula
- Day 3: 50% old formula + 50% new formula
- Day 4: 25% old formula + 75% new formula
- Day 5: 0% old formula + 100% new formula
In this span of 5 days, make sure to monitor your baby closely, and watch out for any adverse reactions.
- Watch out for reactions
While switching formulas, it is common for your baby to have a few temporary side effects. Changing formulas might lead to your baby fussing temporarily. You might also notice changes in poop consistency and colour, and increased gas. These symptoms typically resolve in a day or two.
However, if you notice serious reactions like vomiting, increased constipation, hives, rashes, or blood in your baby’s poop, stop the new formula immediately and reach out to your doctor.
Once you switch formulas, monitor your baby’s weight periodically. Usually, babies gain an ounce a day until they are 3 months old. By 5-6 months, they should double their birth weight. If you notice any inconsistencies in your baby’s weight, consult your paediatrician.
When should you switch your baby’s formula?
Your doctor may decide to switch your baby’s formula for several reasons. Allergic reactions and lactose intolerance are the most common reasons to switch formulas. Some doctors may switch formulas for nutritional reasons as well – your baby may require more of a particular additive. If you notice the following reactions in your baby, it might be time to change formulas:
- Spitting up often
- Hard poops
- Blood in the poop
- Crying excessively
- Not drinking enough formula
- Watery poops
- Rashes and hives
- Disturbed sleep
- Excessive gas
Closing Thoughts
Switching formulas can be stressful as your baby may be fussy. However, remember that every baby’s needs are unique. Keep your doctor in the loop, and don’t forget to give your little one some extra love and cuddles during this time!
