Baby spitting up milk

Hello! As long as baby is steadily gaining weight, spit up is normal in newborns because their sphincter isn't fully developed and can't hold the milk in when it comes up due to reflux. However, if you are bottle feeding you might want to check whether the bottle teat you are using is too fast for baby and size down accordingly. Remember to "pop" the bottle so that air is removed and you might also want to look up paced feeding if you aren't already doing so! Always check back with paediatrician if you have any further concerns and if baby is no longer feeding well!
