It is common for infants to have sensitive digestive systems when trying new foods for the first time. If your baby has experienced vomiting with curd or formula, consider pausing the introduction of that specific food for a few weeks to let their system rest and mature. Always ensure that homemade curd is served at room temperature rather than straight from the fridge, as temperature can sometimes impact digestion. If vomiting persists or is accompanied by other symptoms like fever or lethargy, it is best to consult your pediatrician to rule out sensitivities or potential lactose intolerance.
