Hello Nantap. This is likely colic. Although not medically proven, people use gripe water, Nospamin etc. However, work on your own diet, take enough fluids and balanced diet to make your breast milk rich. Let your baby belch after feeding. Get a growth chart from health center, weigh your baby to see if she's gaining weight. Lastly, 'doctor Bella', biko don't use hot water to massage the navel. It's not the navel.
