Spit up happens. And when it does, it's ok. You don't need to re-serve Evivo if your baby spits up. Just pick up where you left off and give your baby Evivo tomorrow. We recommend giving baby Evivo + breast milk via the syringe in the side of baby’s cheek or towards the back of baby’s mouth; it may take a few feedings for your baby to get comfortable with the syringe. We recommend giving baby Evivo + breast milk before a feeding.
