He has no particular fixed name. But His names are there according to His different activities. Just like His name is Devakī-nandana. Because He accepted Devakī as His mother, therefore He is called Devakī-nandana. Similarly, He is called Nanda-nandana, Yaśodā-nandana, Vrajendra-nandana—in relationship with Nanda Mahārāja, Yaśodā, His foster father and mother.
