Baby Being Sick After Every Feed. The most common cause of vomiting in children and babies is gastroenteritis. You notice your baby spitting this way quickly after a feeding.
Sometimes its straight after a feed. In some cases first symptoms can take up to two months to start. Only a few babies have GORD and it usually affects premature babies more than full-term babies.
The vomiting often starts like a normal vomit and milk just dribbles down the front of the baby.
If baby is projectile vomiting the entire feed after every feed and is also suffering from constipation or not producing as many wet nappies then they need to be checked over by a doctor for pyloric stenosis although this is very unlikely in your case as it does not normally occur until 4-6 weeks of age. In most cases it will last no longer than one to two days and isnt a sign of anything serious. While most spit up is normal it is important to know the signs of abnormal spit up so that you can report these occurrences to your pediatrician. As long as hes gaining weight its normal.
