It's the same way Sasuke's chakra levels grew from vs Itachi to the 4th War despite losing Orochimaru. With age and in time Sasuke's reserves grew, he has the EMS and the Rinnegan combined with his technique refinery he should easily have been able to grow his chakra levels up to adulthood and that seems completely possible. I mean look at the chakra level growth they got between the ages of 12 and 16 alone. Growing chakra levels is not something that would be hard to factor, especially for two re-incarnates.
