how much amount of vomiting is normal for 21 days old baby??

A. hi usually it is normal among young babies to spit up milk in curdy consistency with slow flow. but the amount is not that much. please offer small and frequent feeds. keep your child head slightly elevated while feeding. burp or hold your child on your shoulder in upright position after each feeding for 10 to 15 minutes as you are nursing mother,eat easy to digest food. but if your child spit up milk in liquid or Watery form in larger quantity then please consult your pediatrician.
