PnF : Mother knows best (Private with zgwrox)
 

It was a normal day in Danville. Nothing too special, not even the Flynn-Fletcher boys came up with anything. For fact, it was even too quiet in the house, as Lawrence and Candace left for a couple of weeks for father/daughter bonding, with Candace especially asking her brothers not to get on their mother's nerves too much before leaving.
Linda just finished up cleaning the attic, when she found a box with baby stuff, dropping it on the living room, as she started going through it

Phineas and Ferb walked in to see their mom looking at their old baby stuff.
Phineas: Hey, mom. What's that?

Linda smiled at her sons
Lin : Oh, that? Just some of your old baby things. Neither me or your dad could bring ourselves to get rid of them
Linda picked up a little T-shirt, chuckling at it
Lin : I still can't believe you were that small

Phineas: We used to look so cute in those! I would like to be a baby again!
Ferb: Me, too!

Linda was a bit surprised by that, but a smile grew on her face
Lin : I do miss my babies too...

The boys giggled and laid down on the table.
Phineas: We're ready, mommy!

Linda chuckled, bit then realized
Lin : But we don't have any baby things. Ones, that left are too small for you... I'll look those up on internet, but let's put you in those old pull-ups, from your bed-wetting days

Phineas: Okay, mommy!
Ferb smiled and put his thumb in his mouth as he began to suckle.

Linda chuckled at two of them, before she got out two pull-ups, with prints of cars, and put them on her sons with adding baby powder as well
Lin : There. All nice and dry. Now, my little ones can have no fear of having an accident over themselves
Linda tickled boys on their tummies

The boys giggled as they were tickled.
Phineas: So, should we go shopping for some new clothes?

Lin : Well... I suppose we could, but I don't think we'd find something very baby-like. Maybe we'll find something that will make you look like toddlers, I'll look some baby clothes as well with diapers. And some furniture. You'll need a new cribs and high chairs too

Ferb: What will we do in the meantime?

Lin : Well... I suppose your old baby toys can be good for now. What do you say?

Phineas and Ferb giggled like the babies they were and started playing with their baby toys.

Linda smiled, as she kissed both of them on top of their heads

After a while, the boys fell asleep on the couch.

Linda walked to check on the boys, smiling at them as she saw them both asleep
Lin : Right... nap time for you two...
Linda picked both of them up, before taking them to their room, laying them on their beds, that now had little walls out of pillows, so the boys wouldn't roll out of them
Lin : Good thing the cribs will be arrived tomorrow. The spare room will do just fine for the nursery
Linda gave the boys two pacifiers, they were a bit small, but would do for now

The boys happily sucked their pacis as they slept.

Linda went to do her things, some of which was putting up some of old baby proofing to make sure the boys were safe to play around until they get a playpen, before she looked up the time. It's been almost 3 hours since the boys fell asleep
Lin : Time to wake them up. Wouldn't want them to stay up for whole night
Linda went up to boys' room and started carefully rubbing Ferb on his back
Lin : Hello, sweetheart... time to wake up...

The boys yawned as they woke up.
Phineas: We slept great, mommy!
Ferb: Did you get us any new stuff?

Linda nodded
Lin : Yes, I did. It'll arrive tomorrow morning, so I'll set the nursery for you while you'll be still asleep

Phineas: Sounds good!
Ferb: What's for dinner, mommy?

Lin : Well... I'm not sure. What would you two like?

Phineas: Um... pasta!

Linda nodded
Lin : Pasta it is then, boys!
Linda picked both her sons up, holding them close

Phineas and Ferb giggled and clapped their hands like the babies they were.

Lin: But before that... does either of you need a change?

Phineas: I do, mommy!
Ferb: Change me, please!

Linda smiled, as she sat the two boys on floor, laying out the changing mat, laying out the spare pull-ups and other changing supplies out
Lin : Who's first?

Phineas: Me first, mommy!

Linda nodded, smiling
Lin : Of course, sweetie. Come now
Linda laid Phineas down on his back, changing him into a clean pull-up

Phineas giggled as he looked as his pull-up.
Ferb: Me next, mommy!

Linda smiled, nodding
Lin : Of course, dear. Now...
Linda sat Phineas aside, kissing top of his head
Lin : Sit here while I change your brother

Ferb giggled as he laid on the changing table.

Linda smiled, as she started changing him
Lin : Hopefully, this will be your last change on this table, it's probably not that comfortable with it being for normal babies and you two physically too big for it

Phineas began sucking his thumb.
Ferb: Changies?

Lin : Almost done, sweetheart
Linda chuckled, before putting anew pull-up on her son, picking him up and kissing his cheek

Ferb looked at his new pull-up before hugging Linda.

Linda hugged him back, smiling

Phineas crawled up to Linda.
Phineas: Pasta?
