[SIZE=8pt] ok my tamagotchi and my brother's tamagotchi are both adults, have 4 hearts on each other, and they like kiss when they visit each other... What am i missing anything or why are they not mating yet? [/SIZE]
Actually sweet as sugar, they don't have to be 6 years old. They can be younger than that. They have to be at least over 3 years old and connect with each other many times. After 24 hours, they will mate.
