New infant update rant

Hmm... that math means they're certainly unlikely to see teenage grandchildren, doesn't it? And both they and their kids will have to hurry to see any grandkids.

Don't forget college is at least 3 weeks - the way I play it, usually 4. So if you enroll as soon as you start the game, go all in at 4 classes per semester, and get pregnant the same day as your college graduation...21 days of college + 3 days pregnancy and you have a baby on your birthday to become an adult. Your teen still has 13 days left as a teen when you become an elder; elder life stage is apparently around 14 days, so you'll probably see your first kid become an adult but no guarantee.

Edit: Or is this not updated yet? I though it was since they had the infants in the chart, but it looks like the note about expanded life stages is still from high school. I'm going to hope it's just not updated yet and that 57 days as young adult and adult are from the pre-infant numbers.

It wasn't updated.

Edit 2: The new math

2 days as a baby + 5 as infant + 7 as toddler + 14 as child + 21 as teen = 49 days

28 as young adult + 42 as adult = 70 days

~15 as elder

So now, if you can have 21 days of college, wait 3 days to find a partner/settle, 3 days pregnancy and your first child is still born before you age up.

Then that child will still have 6 days left as a teen when the first Sim becomes an elder, and you'll probably see them become an adult. So you can't have your Sim go to college AND their child go to college and still see grandkids while the first Sim is alive, but at least there's a little more wiggle room. Plenty of time if you don't play with college... or turn aging off while they're in college which I should probably just start doing.

Leaving college out - let's say you play a Sim week before having a kid. Then 3 days pregnancy, then baby, infant, toddler, child... you become an adult 4 days into the child stage... teen, young adult. Your Sim still has 11 days left before becoming an elder. Even if the kid also waits a week before deciding to have a baby, the first grand kid would be born the day before they become an elder. You may not see them become a child though.

Focusing on family gameplay and having young adults get pregnant within a few days of becoming young adult? Grandparent will see their first grandkid become a teen.
