its not a stupid question. when your first tama has a baby the second night it sleeps with the baby it will go back home to its planet and leave you to take care of the baby which will be the second generation of your tamagotchis. get it. if you don;t understand please PM me and i will describe it to you in better detail. i have three tamagotchis and 2 of em are 2nd gen and 1 of em is 4thgen
it is both its how many tamagotchis did u have in this family like ure maybe generation MANY in ure family cus ure mom and father had u and thers mummy and father and so on..like that
If your tamagotchi is gen 1 and it has a child, that child will be gen 2. And when THAT one has a child, its baby will be the 3rd generation, and so on.
