Shed cycles depend on growth rate. Not really age.
Every snake grows at a different pace.
I have 4 girls that are the same age grow at totally different rates. One outgrew the others by 1000 grams in less than a year on the same size food and eating schedule.
They all shed differently as a result of the growth rate difference.
A faster grower will shed more often than a slower grower. Mine range between once every 3 weeks to once every 2 months.
How much does your snake weigh?
I've noticed that BP slow their growing at around 700-1000 grams.
