It’s a common hazard of parenting. You’re ready to leave the house, cleaned up and dressed up, when your baby suddenly spits a blob of drippy, smelly curdled milk all over your shoulder.
Yuck. Why does my baby spit up and how can I prevent this from happening? Alzein Pediatrics explains here.
“Spit happens” because babies are born with an immature lower esophageal sphincter (LES). This muscle is located where your baby’s esophagus, the tube that carries food from the throat to the stomach, meets the stomach. In new babies, the LES is not yet strong enough to close tightly to seal the stomach from the esophagus, so stomach contents flow back into the esophagus, into the throat and out of mouth. This is known as infant reflux or infant acid reflux.
About 50% of healthy babies experience infant reflux and will spit up after meals. While it seems like spitting up can last forever, and some LES muscles take nearly a year to fully mature, many infants will stop spitting up by the time they are about 7 months old and can sit upright without help.
When that spit up dribbles down your baby’s front, you may worry that your child is losing most of what he or she just ate. In reality, normal spit up is just a teaspoon or two. Rest assured your baby is typically still getting all the nutrition she needs.
It’s important to distinguish between spit up and vomiting. When your child spits up, she hardly notices it, and will still play or laugh without missing a beat. The spit up just dribbles out, often prompted by a burp. Vomit, on the other hand, spews out with force, shooting out of his mouth and causing your child to react with distress as if in pain.
A weak LES is also what causes gastrointestinal reflux disease in adults, resulting in heartburn. This connection has caused an increase in the prescribing of acid-suppressing medicines for infants. Before any such drastic measures are taken, we will give your baby a full exam, including carefully checking weight gain progress. Very few babies will require a prescription for spitting up.
You can’t eliminate spit up entirely until your child’s LES matures, but you can do a few things to help lessen the occurrence.
While most spit up is perfectly normal, there are times to be concerned. It’s time to call Alzein Pediatrics when:
