What Changes Are Normal?

This section helps to addresses some common worries when a previous formula is switched out for a new one, especially if the characteristics of the new formula are significantly different than the previous one (i.e. switching from cow to goat milk).

Stool color

May change. Depending on the previous formula and what the new formula is can determine changes in stool color. While changes in color are normal, they should be monitored over a few days including any fussiness or discomfort shown by baby.

Stool consistency

Similar to changes in color, consistency can change depending on the change in formula. For example, changing from cow to goat formula can commonly lead to looser stools due to the easier digestion of goat milk. Again, monitor over a few days and baby's behavior during this time.

Gas

Baby's digestive system. especially newborns or early infants, is not well-developed and can respond negatively to dietary (formula) changes. Gas or bloating can increase temporarily during a formula change. This is usually for a short time but should be monitored closely for discomfort.

Appetite

Some babies take a little time to adjust to changes in formula and may adjust their feeding behavior at first. But if the change in formula was important, most babies will adapt to the new formula especially using the gradual approach from the transition table above.

Taste

Depending on the baby, there may be some aversion to changes in taste between formulas. If possible, stick to the same company's formula when transitioning to reduce taste differences. If not, follow the transition schedule provided above and let time work in your favor. 

When to Contact Your Pediatrician

Obviously, we are not medical professionals and the information presented here is meant to be educational and not actual medical advice. With that in mind, you need to contact your healthcare provider if baby has any of the following symptoms:

• Persistent vomiting
• Blood in the stool
• Signs of dehydration
• Difficulty feeding
• Symptoms that are severe, worsening, or concerning

 

A Transition Schedule

If you are switching formulas or using combination feeding (breastmilk + formula), your baby might prefer a transition period. Use this as a guide to assist the transition.

You may need to adjust the percentages each day depending on your needs. Keep in mind gradual transition is just fine as long as nutritional needs are being met. There should be an 'end goal' to complete the transition after a week or so.
