My husband has been asked to be our oldest nephew's godfather. He is chuffed to bits about it. 
But our younger niece/nephew are getting christened at the same time-my understanding is that each child will have 2 godparents..our issue is..
What is the etiquette when buying gifts? Do we buy something for the younger ones as well when they'll have their own godparents?
Google isn't giving clear answers.. x
