>>> we've got an update now on a very large family we met last fall. with the arrival of quintuplets, they went from four kids to nine overnight. now they're all under one roof. kristen dahlgren paid them a visit.
>> reporter: welcome to the home of quintuplets. that's 3-year-old derek keeping tabs. there's also 2-year-old twins dallas and denver and 8-year-old darin.
>> is it hard to keep track?
>> yes, it is hard. i won't even lie. it's hard.
>> dion and nevon always wished for a big family.
>> look at you guys, you're still smiling.
>> reporter: life has changed since the quints left intensive care for their las vegas home.
>> they've gotten so big.

>> i don't want any of them to grow up thinking they didn't get enough love.
>> that doesn't seem to be a problem. the older kids can't get enough of the quints, even helping out.
>> i'm starting to smell something. you got this?
>> i got it. i can handle it.
>> so with them all handling it so well, could there be even more some day? they're not ruling it out. but for now --
>> i'm on strike. i'm on strike.
>> i tell people, do not try this at home.
>> they look so peaceful in that last shot.
>> they've got the right attitude.
>> they do. what a great family.
>> and so does kristen passing off the diapers.
>>> up next, we've got a man who only ate mcdonald's for 90 days and he lost nearly 40 pounds doing it.
>>> and then,
