Here we have, Supergirl, Bat Girl, Scarlet Witch, and Ms. Marvel as babies in the playpen together.

(This is a story that he came up with or what's going on that is)

They were following a villain to a warehouse where it was a trap for the four girls, using a magical spell which turned them into 8-month-old babies, even changing their clothes to suit their age. Once the babies were found by Wonder Woman and some other adult heroes, they agreed that until they were restored to normal, they’ll babysit.

Let’s just the babysitters are prepared for babies who still have their powers.
