Psychologists have created world's first universal charts for normal amount of crying in babies during first three months. On average, babies around the world cry for around 2 hours per day in first two weeks, peak at 2 hours 15 mins at six weeks -- and crying reduces to 1 hour 10 minutes by week twelve. Their study found that babies cry more in Britain, Canada and Italy, than the rest of the world, according to new research. In Denmark, Germany and Japan, parents deal with the least amount of crying and fussing.
