Your tamagotchi usually needs to be unpaused for about 24 hours-the adult with the baby.
Be patient and have your tamagotchi be unpaused for at least 24 hours. Then, turn the time to 11:59 P.M (the adult still with the baby) and go back to the normal screen. (Keep your tama unpaused) Soon, in about a minute, the light should go on and the adult should get out of bed and stare at the sleeping baby for a bit. Wait. Soon, the adult should lift into the air and out of the screen. The baby is still sleeping-but without the adult!
You can turn the time to the morning, about 9:00 A.M and go to the normal screen -unpaused. You can name the baby and then play with it - which means you began another tamagotchi generation!
Hope you understand,
