Depends on the snake. My babies grew 50-100 g a month.
Once I had 4 female hatchings born in the same month that were fed on the same schedule. The oldest is the smallest. The youngest outgrew the other 3 by double the first year.
The older 3 averaged at about 500 g by year 1. The youngest was at 1200g at the same time.
Every snake is different.
