HI Bhaskar Thank you for your query Junior Lanzol and Domstal both are very safe drugs, so you first need to shed your anxiety about that. Secondly, these can be the symptoms of GERD. Apart from the drug therapy, certain measures at home will help. Try not to give too much at one time. Instead spread the diet into small frequent helpings. Keep your child propped up, which means the head should be above the rest of the body with an angle of at least 45 degrees at the waist. There are simple car seats available at toy shops. You can nurse your baby in that. Else use pillows at all the times. Try to keep your baby upright especially after meals. Prefer semisolids over pure liquids. And avoid large feeds just before sleeping. Try to give them a good two three hours before your child normally goes to sleep. Two tests can diagnose GER. One is a GER scan and another is a Barium swallow. But if the child improves you need not go for these. Else consult a pediatric surgeon Hope that helps God bless you
