According to MedlinePlus, simethicone drops, which help break up gas bubbles, are safe for babies as the body does not absorb the solution. MedicineNet suggests using no more than 12 doses of simethicone per day if treating a child without direction from a doctor.
Simethicone drops are available without a prescription and can be administered to infants orally as needed. According to MedicineNet, the solution should be administered very slowly into the infant's mouth and combined with an ounce of infant formula or cool water. Simethicone drops are generally given to babies after meals or at bedtime, and the appropriate dosage depends on the age and weight of the child.
