Acid reflux in babies depends on his/her position and activity level after eating. Keep the baby upright either in a sling or soft carrier and avoid bouncing or exciting the baby. It is good to keep the baby happy as crying aggravates acid reflux in babies. In addition breast feeding the baby helps avoid acid reflux as it is easily digested, so it is good to not abstain from frequent feeding that nursing involves.
If baby formula is unavoidable it pays to feed the baby milk and baby food more frequently at regular intervals. Ensuring comfort with dressing the baby in loose and comfortable clothes helps. A sleeping wedge would prove useful, with a baby hammock designed for babies with acid reflux proving useful. Also baby hammocks replicate the womb environment and provide security to the baby.
Visit a pediatrician for a prescription if all these measures fail.
