If a breastfed infant is introduced to formula once a day, is it necessary to continue daily formula feeds, or can they be spaced every two or three days?
Hello,
My baby is breastfed, and breastfeeding got off to a very good start. My goal was to exclusively breastfeed, but I also needed to be able to take an occasional break.
At first, we planned for my partner to give an occasional bottle of expressed breast milk. However, I quickly realized that pumping regularly was a significant mental burden for me and was not something I could realistically sustain.
Our maternal and child health nurse suggested introducing a bottle of infant formula so that my partner could occasionally take over a feeding. Since then, my baby has been receiving one bottle of cow's milk-based infant formula every day.
I've read that, once cow's milk proteins have been introduced, regular exposure may help maintain tolerance and reduce the risk of developing a cow's milk protein allergy. However, I haven't been able to find clear information about how frequent that exposure actually needs to be.
My question is: is it really necessary to give a bottle of formula every day to maintain tolerance, or would less frequent exposure—such as every other day, every third day, or even once or twice a week—be sufficient while continuing to breastfeed? Are there any evidence-based recommendations or studies that address the minimum frequency of exposure needed?
Thank you very much for your help.
