Well... When your tamagotchi egg hatches, it's a baby. An hour later, it's a child. Next day, at the same time your baby evolved, it will be a teenager. Next day, the same time when your child evolved, it will be an adult. If you wait untill your tamagotchi is for or five years old, the band manager will come to bring you a partner which will suit you tamagotchi. Your tamagotchi does not have to have a baby if you don't want it to, you just click no when the band manager comes. This will mean, though, that your tamagotchi will grow old, and die, eventually. You need to have a baby on your tamagotchi toy to carry on the generation. Unfortunately, there is NO growth chart at the moment. I'm trying to make one, though. As soon as i see one i will let cha know. Hope i helped,
