Yes,unpausing your tamagotchi will slow down it's ageing process,and waste the batteries.Also it will take more time cause since all day and unpause at night!,That's crazy!The best way is tostart over,or keep with that and will take a while to age.
My name is Calvin! Lol. Anyways, If you have an adult, it will grow One Year old faster then Child or Teen. If you pause the whole day it will not turn the age you were expecting it to.
