How long does it take for a Tamagotchi Music Star V6 to grow into a baby then a toddler then a child then a teenager then an adult and then a senior?

it depends on how well you take care of it.

Sometimes if you pause it and don't play with it then it will not grow. from baby to toddler 1-2 hours from toddler to teen 1 day from teen to adult 1 day and adult to senior 9-10-11 days hope i helped tip: this is how long it will take if you don't pause it if you need to leave it but it in sleep mode by changing the time to bed time that's what i do!! hope i helped again!.
