Very good with kids of all ages, can adjust to various needs, after all he took care of Bruce since he was a baby (when Thomas and Martha were busy).
Loves to read to the littles, he has so many books.
Has a dedicated basket of supplies, especially bathtime stuff for his little(s) (separate baskets for each one).
Gentle but firm. Will wait out tantrums without giving them attention, but is always there to talk it out once they're ready.
Of course, he's a butler, so he already does a lot of smaller things like opening doors etc, but he enjoys it more with the littles.
He sometimes still uses the titles he uses for the littles when they're big (master/miss/lady).
But he also likes "little miss", "little lady", "little one", stuff like that, as well as "poppet", "sweetheart", "dear one/boy/girl", etc.
When he's getting towels for the kids to take baths he'll fold them into towel animals.
Always prepared. Most of the batfam don't know there's a diaper bag in the trunk of every car he drives... Until they need it.
Generally most of the littles aren't allowed in the kitchen. Most of the household isn't allowed in the kitchen anyway, but there are some exceptions who are banned when little.
Except for Jason, who is inexplicably well-behaved when he gets to "help" (actual amount of assistance varies on age) Alfred cook.
I imagine Alfred probably comes from a working class family, I know he was in the military before being a butler but I don't know what his social status was like.
But anyway I mention that bc I think he'd have the kids watch the public access shows.
They can afford whatever shows they want but he WILL put on Mr Rogers.
Strong enough to carry even the heaviest of his kids, like Jason; will carry them around on his hip like they're still small.
He hangs every piece of art the kids give him on the fridge until the fridge gets too full and then he puts all of it in boxes that he keeps stored away so they won't get damaged.
(yes this is inspired by that detail in The Batman 2022 where Alfred has a kid's drawing from Bruce stuck to his mirror.)
He's not the most energetic caretaker, he's usually not the one running around playing with the kids. But he's always there if you need company.
Will put his suit jacket over the kiddos' shoulders. Usually when they're cold or upset but they don't have to be. If you're little there is always a chance. He thinks it's cute how they'll kinda snuggle into it.
Will set up the littles' toys to make it look like they've moved while the kid was out of the room.
Buys the kids expensive stuff, not like stuff that's just expensive for the hell of it, but he's got Bruce's money and permission. If it's good quality and the kid wants/needs it he'll buy it. (Usually this is stuff like clothes and toys, and he's more strict if they're out at the store because he knows how marketing works. And also because he's not going to buy something that's just going to fall apart, he'll buy a better quality version later.)
Bedtime master, all the kids listen to him when he says it's bedtime, also he makes the best nighttime bottles.
Prefers tactile toys with natural colors. He'll get colorful stuff of course, but for toys it's probably not going to be bright neon unless it's something they requested.
Has one of those play kitchens set up for the kids who aren't allowed to help him in the kitchen.
The master of repairing and washing favorite stuffies and blankets before anyone notices they're gone
Prefers "papa" or "grampa" over other familial terms, he likes to say he's too old to be anyone's dad (except Bruce, Bruce is allowed to call him dad).
