No they don't.
In the UK, and also Europe since October 1998, children have needed their own passport and can no longer travel under their parents passports.In most other countries it is highly recommended that children have their own passports.If children are under the age of 18 they do not need a passport, for Ireland, however you will need their birth certificate. Anyone over the age of 18 will need a passport for Ireland.
As Belfast is in the United Kingdom and Dublin is in the Republic of Ireland, technically you may need a visa or passport to go there, depending on your nationality or other factors. However, there are no passport checks done on the train. Usually if you have been allowed access to Northern Ireland, you will also be allowed to get into the Republic of Ireland, but you need to check. See the website at the link below.
