IIRC the Biblical narrative, after being born, Moses spends 3 months at home and then moving to the royal palace. His mother continues to breastfeed him for a certain period of time but then the link breaks.
Moses grows up, travels the land of Egypt, finally escapes to Midyan and comes back some 40 years later as the ultimate ruler of the Hebrews leading them out of the country to the promised land.
The Torah is usually very emotional about family ties, spending large detailed passages on family reunions, as with Yakov and Eisov, his sons, and more. However, I don't recall anything about Moses meeting his parents or children (after Matan Torah. Related "why-moses-didnt-care-for-his-sons").
The Torah is very explicit and descriptive about Moses meeting his in-law (nothing though about his wife or kids) but stays silent about him meeting his parent.
EDIT (thnx Double): Even if we say that both Amram and Yocheved died before Moses returned to Egypt, according to the Torah, he shows no interest in their fate at all. Besides, Amram being Gdol Hador it would be reasonable to mention his death and burial.
Did Moses meet his parents after the separation when before or after his escape? And why does the Torah totally omit such a sentimental story?
I personally feel that the "parentless" narrative of the Jewish leader is very purposeful in the story but don't know why.
