Complications: choking on spit up milk, heartburn from acid on lower esophagus, poor weight gain.
Poor closure of the valve at the upper end of the stomach. More than half of all infants have occasional spitting up ("happy spitters").
During the first month of life, newborns with true vomiting need to be seen immediately because the causes can be serious. Therefore, it's important to distinguish between reflux and true vomiting.
Reflux: The following suggest reflux (spitting up): infant previously diagnosed with reflux, onset early in life (85% by 7 days of life), present for several days or weeks, no discomfort during reflux, no diarrhea, hungry, looks well and acts happy.
Vomiting: The following suggest vomiting: uncomfortable during vomiting, new symptom starting today or yesterday, associated diarrhea, projectile or forceful vomiting, looks or acts sick.
If large volume and comes out forcefully, see Vomiting.
Feed smaller amounts.
Give smaller amounts per feeding (at least 1 ounce less than you have been). Keep the total feeding time to less than 20 minutes. (Reason: overfeeding or filling the stomach to capacity always makes spitting up worse).
If the mother has a plentiful milk supply, try nursing on 1 side per feeding and pumping the other side. Alternate sides.
Wait at least 2½ hours between feedings, because it takes that long for the stomach to empty itself. Don't add food to a full stomach.
Avoid tight diapers. It puts added pressure on the stomach. Don't put pressure on the abdomen or play vigorously with your child right after meals.
After meals, try to hold your baby in the upright (vertical) position. Use a front-pack, backpack, or swing for 30 to 60 minutes.
Reduce time in sitting position (e.g. infant seats). After 6 months of age, a jumpy seat is helpful. (The newer ones are stable).
Reflux improves with age. Many babies are better by 7 months of age, after learning to sit well.
