A.C.
My son had reflux from the time he was a newborn until he grew out of it around 18 months.
Here are the common symptoms of GERD (reflux) in infants:
* Frequent spitting up or vomiting
* Irritability when feeding
* Refusing food or eating only small amounts
* Sudden or constant crying (colicky behavior)
* Arching the back while feeding
* "Wet" burps
* Frequent hiccups
* Frequent coughing
* Poor sleep habits with frequent waking
* Bad breath
Sometimes, babies with reflux have a lot of hiccups (but alone, that 'symptom" means little).
I would take your baby to the pediatrician and ask about amounts you should be feeding. breastfed babies don't need as much breastmilk at formula-fed babies need formula, in order to grow; also, its much easier to overfeed a baby when feeding with a bottle.
I would be very concerned about her aspirating the milk/vomit, because this can cause problems like pneumonia.
Some things to try:
* Make sure to feed the baby in a more upright position (at least 30 degree angle, but higher angle is better).
* Keep the baby more upright for at least 30 minutes after each feeding.
* Feed smaller feedings more frequently.
* Elevate the baby's mattress. When I was doing research, there is apparently a foam block you can buy to elevate the mattress, and a harness that you buy that attaches to the crib. We didn't use the harness, but we did elevate our son's crib. We just rolled up some towels and used old pillows under the mattress at one end of the crib.
There are medicines that can be prescribed for the baby, too, if you want to go that route, too. I think Zantec, maybe? We opted to treat it w/o meds, by the recommendation of our pediatrician, but we were late in getting it diagnosed, and it was already starting to get somewhat better... had we figured it out at its worst, we probably would've insisted on the meds, because he was pretty darn miserable.
