The next Mario platformer that has NSMBWii style co-op needs the four babies.

Mario Super Sluggers

The Baby Fan
Wario and Waluigi kidnapped Mario, Luigi, Peach, Daisy and Rosalina. Baby Mario, Baby Luigi, Baby Peach and Baby Daisy must help save them!

-Up to 4 players can take part!
-Online co-op allowed with friends!
-Ride on a Yoshi and help out your friend's baby!

There. The babies appear again after their last appearance in Sluggers. Baby Daisy, Daisy and Waluigi appear outside of a spinoff game for the first time. Online co-op supported. Wario and Waluigi become the main villains for the first time. We get a Yoshi's Island game again. 5 birds killed with only one stone. Problem solved for everybody.

How can you say no to this game?

No.

I'm not a big baby fan, so I'd rather play as the grown counterparts in all cases except that of Waluigi...
 
it's seems very low feasibility
since at first the staff haven't improved their main games at least with main toads recurring or playable
I don't see how can you persuade the staff to make babies to be playable
since they are still "minor" in Mario series

I think if you love babies, ask for the next Yoshi and M&L RPG game in Wii is more reasonable
 
I would so approve of this, except Nintendo would never do this. :(
 
I want a 3D mario game with 4 player co-op, but that would take a while to impletate, and it could fail. They almost got it for Super Mario 64 DS, but they must have scrapped it.
 
That would have been awesome to have 3D multiplayer in Super Mario 64 DS. Too bad it didn't work out for Nintendo it seems. But maybe in the future, it could happen.
 
I would say yes, but:

A: NOT A PLATFORMER.
B: NO BABY DAISY. EVER. I NEVER WANT TO SEE HER MUG AGAIN.
C: IF YOU'RE GOING TO MAKE THE HEROES BABIES, MAKE THE VILLAINS BABIES (i.e. Baby Bowser, Baby Wario, Baby Waluigi, etc.)
D: WHY THE HECK DID YOU INCLUDE ROSALINA?
E: NO YOSHI, UNLESS YOSHI IS ALSO A BABY.
F: ADULTS ARE UNLOCKABLE.
 
A new Yoshi's Island game for consoles would be nice, and they could definitely incorporate features from NSMBWii, but Baby NSMB would just be silly. I'd like to see each Baby and each Yoshi colour have different attributes so you could mix and match special abilities a la Double Dash.
 
I would like babies independent from Yoshi more times.
 
No.

I seriously have nothing more to say on the matter.
