Projectile vomiting refers to when the vomitus is projected quite a distance away. Babies usually projectile vomit when they are sick. If a baby projectile vomits more than once per day and is also not gaining weight, you should see a doctor to rule out the possibility of pyloric stenosis. Pyloric stenosis is a condition where the connection between the stomach and intestines are narrowed. This condition is also rare.
The Vomiting Baby ~ The Impact on the Breastfeeding Relationship
The baby may start to breastfeed more often, which could temporarily increase a mother’s breast milk supply.
The mother might start to wonder if something in her breast milk is causing the problem but this is very unlikely and supplementation will cause increased spitting up.
Try to keep your baby in a more upright position while feeding; this causes
gravity to keep the baby’s stomach contents down and is especially
helpful for babies with acid reflux.
If the mother has oversupply, she can express some milk into a cloth until the flow slows down.
If the baby is sick and seems to only to tolerate small amounts of milk, but he/she still wants to comfort nurse, the mother can pump to reduce the amount of milk in the breast before a feeding.
