My son is 19 months old .... but he always cry at night suddenly ... i checked his diaper its not so wet ... i feed him at night too ... still he cries ... don't know why

hi dear, even though other moms feel it could be colic, i would suggest you try those remedies and also look for other causes. colic usually happens between 2 to 5 months, but your baby is now 19 months, almost heading to the 2nd year, so it is unlikely that it is colic. one reason that could be a possible cause for the pain and discomfort is lactose intolerance, that is if your baby has milk and dairy products, including even breastmilk. our younger one was diagnosed with the same around 10 months of age. often the symptoms are same as colic, but an additional symptom would be difficulty in passing stool. please definitely check with the doc. and in the meantime, massage your baby's navel area with a mix of heeng and water, as it will help release any gas buildup that could cause pain.
