If you get a baby, watch the tamagotchi's clock and on the second night at exactly midnight turn on the light and the mother or father will suddenly wake up and watch the baby sleeping. It watches its baby for about a minute then it turns its head, cries and floats away. It is very sad. I videotaped it to show my friends.
You have to be very careful the next morning as you will be responsible for feeding and cleaning up the babies poop. For the first hour all it does is eat and poop. You have to be right on top of it or the hearts will be empty. Then after about an hour it turns into a toddler and you don't have to watch it as closely.
Good luck! I had one that died for no reason in the first or second generation too. It was well looked after. We never did figure out why it happened. Strange.
