they should not be given on daily basis but should be given only when required.
meet your doctor who will tell you what is the indication and how many times it can be given.
(this applies to anti-colic medicines as well as digestive medicines/ enzymes, gripe water, bonnisan, gutti etc of any branch that is allopathic or homoeopathic or ayurvedic).
Next Steps

it contains sodium bicarbonate as well as plenty of sugars which has got side effects for such a small child.
