She was bristled, ready for another flat out attack-- but Maria apologized, which had Dinah staring blankly for a moment. In all the years that she'd known here and with everything they'd all collectively been through, it may have been the first time she had heard the words "I'm sorry" come from Maria Hill's mouth regarding her own behavior. As the shock wore off, Dinah nodded in acceptance of the apology. She wouldn't pretend that the attack hadn't wounded her-- but it was something she would need to figure out for herself; and whether Dinah liked it or not, Maria had little to no say in that.
"'Nothing to do with' might be a little harsh. It's a baby, not a nuclear weapon silo. There is literally nothing you need to be involved in that you don't want to be." Like Bruce said, they weren't exactly asking her to watch the kid; just be around while they had a kid. "There's not even a hell of a lot Dad gets to do for the first couple months anyway-- just a lot of feeding, pooping and sleeping; and I promise you're off the hook for all of that."
They were also in the extremely privileged position of not only having friends and family who would be happy to babysit once they were feeling comfortable with it-- but Alfred, who would be along for every step of the way, if not to change a few diapers himself then to at least offer advice and counsel when they needed to know how bad of an ant bite meant a trip to the hospital, or if a sniffle was just a head cold or worse.
Dinah found herself looking at Bruce as he went on, a soft smile tugging at the corners of her lips, and she was still looking at him when he glanced to her-- seemingly for confirmation of either whether or not he was a good father, or whether or not he thought he could be both a good father, and Batman. It wasn't a competition Dinah planned to get into-- mostly because some days, she couldn't be sure who would win; but she would do what she could to see that he could have it both ways. In truth, she wanted both for herself as well.
She tore her eyes from him to Maria again, "This isn't a death sentence, Maria. It's not some kind of trap. All we wanted was to tell you what's going on in our lives-- something we're happy about-- and to share our happiness with you. A baby is absolutely going to change our lives; but we'll have to figure that out as we go."
