In small baby reflux or acid peptic disease can occur like adult.
Relaxation or weakening of valve of the stomach and esophagus can cause reflux.
When babies grow up, it usually subsides.
Head end of the bed/cot can be high up to prevent reflux.
Smaller, more frequent feed, changing position or interrupting feedings to burp — can help keep reflux under control.
If the home measures do not help, then treatment with medicine can be needed.

Rice cereal is less allergenic & is usually well tolerated.
Acid reducing agents like ranitidine or zantac, omeprazole, lansoprazole etc. are also used.
