Baby Formula: Switching Formulas


Your baby’s growing (so fast!) and his digestive system is developing, too.

Sunday, July 30th, 2017

As a result, you may be thinking about changing his formula, or perhaps digestive issues like fussiness, gas and spitting up triggered the thought. No matter what, it’s best to speak with your doctor before switching your baby’s formula, while keeping these next few pointers in mind:

  • Don’t worry about alternating or combining the new formula with the formula you’ve been using:  Baby’s transition to the new formula can happen right away.
  • Avoid mixing different formulas! Here’s why it’s not recommended: Formulas aren’t meant to be combined. Plus, if your baby experiences digestive issues, you won’t be able to identify the cause.
  • Give your baby 3 to 5 days to get used to the new formula: It may take him some time to adapt. (Though he may even adjust right away. Yay!) While you’re transitioning, your baby may go through some other slight changes—mainly to his stool pattern, gas and how often he spits up. Don’t worry, though, this is normal!

Remember, you should consult with your baby's doctor before switching formulas, so you can always raise any other questions or concerns at that time.
