My 20 month old baby girl has been getting up crying at night around 12 - 1 am with very tight stomach. Some days she is fine after giving colic aid but some days she pukes. Her diet has not changed. Her paediatric had given her Lanzole Junior for 5 days and also worm medicine but nothing has helped. Another paediatric suggested that since i have gas she gets gas. Please suggest what to do.
