Years later, when the Clone Wars begin, Maul is... admittedly discouraged. He knows how important his job is, but then he starts thinking about how he is essentially putting young children into an institution that is training them for war. (Sith's Hells, Skywalker was just given a padawan, and she looks like she's barely past her Gathering! Not to mention the clones, who seem to have only existed for a decade.) So, for a while, he is conflicted.
He even calls his Master, Plo Koon, to ask for advice. And afterwards, he knows what he needs to do.
So, for a time, he decides to work in the crèche instead. It's not as exciting as his old job, and he still gets visions (read: nightmares) once a week. But maybe, if he can be there to prepare them, teach them. Maybe it can help. And the Jedi need all the help they can get.
On the rare occasion that Obi-Wan returns to Coruscant, he looks... well. To most people he might look fine. But to Maul... they've known each other since they were toddlers. And his old crèchemate looks so tired. So close to breaking that the younger jedi shudders everytime he sees the newly appointed General Kenobi. It makes him glad that he has no business on the frontlines.
The only thing that remains untainted by the war is the young children under his charge.
Admittedly, it had definitely required some getting used to. Before, he was delivering younglings barely over the age of two. They sat quietly in the ship, marveling at the lights of hyperspace, or sleeping, or, if they got fussy, Maul would push calm and weariness into their minds and they would drift off until they arrived.
But the younglings now. They weren't toddlers any longer, nor teenagers. Not yet. The oldest among them were around the age Skywalker had been when he arrived, most of them a couple years younger. And they were so much... more. Loud and excited and always getting themselves into trouble! He could deal with the missions that came from his old job. Usually, he barely had to speak to the adults involved; whether it was to the parents saying their goodbyes (he only offered quick, but genuine assurances that their children would be taken care of,) or the complications (to them, he stayed absolutely silent until they were taken care of.)
Now, he was a teacher and a caretaker, and that had to require conversation and interaction. And with children, he assumed that would be more difficult.
The children immediately flocked to him, wondering about his adventures around the galaxy, asking to see his lightsaber, and using him as their own personal jungle gym, all the while complimenting his horns.
On a regular visit to the crèche, you can find Maul surrounded by children listening for story time, or carefully critiquing their form with the training sabers. When they take walks through the Temple, you can even see him carrying some of them. (One in each arm and one on his back.)
And for a while, the visions, and the guilt and fear they brought him, abated.
