Congrats on getting back to work. Your baby can still benefit from Evivo if you are able to pump and store your breast milk for some or all of your baby's feedings. Evivo works together with the milk oligosaccharides from breast milk to restore the infant gut microbiome to its original natural state. Evivo needs these milk oligosaccharides to be 100% effective. So pump away and store that breast milk, so you can continue feeding your baby with Evivo once a day, every day.
