How and when do sims grow up in Sims 2 for p.c.? Baby, teen,adult?

like if you're a baby you have 4 sim (i think it's 4)days to be a baby, then when the 4 days pass you grow up, then you're a child for a certain number of days, then you grow up again, and it goes on until you're sim dies. (when you're an adult you have about 25 days till you're elder) first there's a stage of just born baby (it's not even selectable then), then a toddler, a child, a teen ( then a young adult-if you have university), then adult and finally elder.... then you die....

Baby- I think 3 days Toddler- 4 Days Kid- 7 days Teenager- 15 days Adult- 29 days Elder- Until you die!

woman pregnant -3 days-- baby -3 days-- toddler -3 days-- child ~6 days -- teenager ~15 days -- adult ~28 days-- elder ....days

the total amount of days in their life is between 60 and 80 unless u get that life extension thing or die, etc. but i think that a baby is only a baby for about 2 or 3 days and a toddler maybe 5 or 6 then a regular child stays that way for maybe a week . a teenager takes between 2 and 3 weeks to bacome an adult unless u have sims university and send them to college. an adult will stick around for 20 or 30 days. afterwards your sim as an elder will stay there for roughly the same amount as adult, maybe less. his/her life meter will also show instead of the levels of age and the amount of time left before he/she goes to the next age level, how long they've been around

Pregnant~ 3 days Baby~ 3 days Toddler~ 3 days Child~ 7 days Teenager~ 15 days

it goes to baby, toddler, kid, teen, if u have the college one then young adult, then adult

Omg it's like baby 3 days toddler 4 days child 8 days teen 16 days adult 24 days although I always get bored during teen age so I send them to college to get it over with and become an adult
