If a baby drinks formula and spits up milk, you should give the baby some probiotics or burp the baby after eating formula. Sometimes it is normal to spit up milk after eating formula because the baby’s stomach is in a horizontal position and lying down immediately after eating milk can easily cause spitting up. In this case, you should burp your baby after eating milk, and if you can’t get it out, hold it vertically for 20 minutes before putting it down. There is also a situation caused by indigestion in babies, milk powder is not as well digested and absorbed as breast milk, too many feedings and too short intervals can cause indigestion and vomiting in babies. If necessary, let your baby take some probiotics to regulate the balance of intestinal flora.
