Of course gripe water works very well to relieve the painful trapped wind in babies, though you need to help them still bring it up, by rubbing and patting the back. The manufacturing is of different qualities and ingredients these days, everyone trying to ride on the success of Gripe water since the mid 1800.
The main fact is that babies do cry for many reasons, wind being only one, colic is more sever but gripe water gives relief of many ailments even in adults.
Though i would tend in my day, to give a couple of ounce of gripe water, after a bottle, to my own kids, as the stomach lining of babies takes around 3 years to adapt to all the rubbish on the market. So avoid giving 2 year olds' fizzy acidic beverages.
Most babies want the attention and will cry anyway, its their natural survival instinct to manipulate parents, so get to understand the difference....time to sleep means sleep so a 5 to 10 minute wailing session is expected if left alone, which is not a good method.
Have body contact until the baby falls asleep, they normally will after a good feed and winding and a cuddle. If you do not wind, then expect a baby to cry in pain.
Just my 10 cents from a daddy.
The other thing is different cultures have different methods, for stomache ailments in babies, don't be afraid to learn them, they may come in very handy.
