it's technically not pausing, but if you set yuor tama to the time when it's asleep, then it wont need you (as if on pause) and it will continue growing. Hope I helped!
i think you could set it to the time it sleep syou can do whatever you want whilst it is then wake it up again it has nuthing to do with the age because sleeping is a tamagotchis natutral habbits paussing stops it from againg as you all no so the best thing to do is put it to sleep
