IRCTC (The Indian Railway online ticket booking agency) provides an option to specify details of children under five years of age who are travelling with the ticketed passengers.
While booking a ticket through IRCTC, I have forgotten to fill in the personal information of my children (both under 5) in the form. One child is 3 years and another is 4.5 years old. Will they be allowed to travel with me or can it lead to a problem during boarding/journey?
