I feel like Bumblebee would get babu Sari a little bee onesie
Oh yes he does, he so so does it, makes sure the others can see how she makes the little grabby hands for it.
It's a competition to see which one of their colors/themes she likes the best when they all go out together so she has "interact with the outside world" time.
Each and every time, they hit up a clothing store, never to get anything for themselves no, they can just make any outfit they want with their holoforms, it's all for SARI, and DOMINANCE within their group.
Who is the favorite? whos colors does she love the most? Who gets her the best stuff?
It's as one does when a baby chooses something uniquely you, I know me and my family flaunt the superiority when the baby chooses one of us over the other (lesser) choice, ((the not me choice)), so within the store, Bumblebee is the most obvious. I mean, he's already got the yellow, she already loves yellow, so automatically he's got majority points! She just needs the stripes!
Queue a very young looking boy(teen? Man? Eh, the cashier doesn't care) slamming his hands down on the counter talking about "every bumblebee or bee related piece of clothing you got", staring at them like they don't get paid fifteen dollars an hour.
Meanwhile prowls trying looking at the golden bracelets, and maybe that tacky little onesie that says "mamas gurl" in gold letters on the back, but it's main color is... Pink. Pink and gold. Even in his holoform he doesn't think he can pull that off without looking like Patricia. She rocked the pink and gold jewelry like it made her queen of the world. He put the onesie back, no way was she going to have Sari resemble Patricia of all people. Maybe they can get matching bows, Sari likes to mess with the one on her collar when walking around.
She picks out a little black bow and ties it to one of her pigtails. Prowl will take it off when they need to pay for it. It matches with the glasses they share.
Bulkhead is just as obvious as Bee, but less so with the competition part. He goes, surprisingly enough, with what she already has in her closet. Hes trying to make complete outfits, he likes to match his own with Saris, little green shoes with a yellow dress and green jacket? He's wearing a yellow undershirt and shorts, a green letterman Jacket, and a pair of sneakers cuz they are comfy and basic and versatile. No, Bee, he won't wear Crocs, fundamentally, they're not as versatile as he needs sports mode be damned
Ratchet is really good at it, necessities like bibs and socks, they have his colors. I haven't really noticed but on non gendered stuff for babies, red and white are actually very common colors. So long as the red is an accent and not a main color. (And not Elmo.) He doesn't brag about how much she really really loves the doctor toy set he got her a few weeks ago, he does grin smugly at Optimus when his thing is set aside for a few moments to play doctor with grandpa Ratchet though.
The prime, well, Optimus doesn't know how to go about it. The one thing they've got in the whole "favorite" category would have to be the red little truck that she loves to carry around everywhere. He made it, actually. The kid in their favorite store, Miko, was making something at the counter one day, needles thread, little beads and stuffing, the whole shebang.
He would have asked about it if Sari wasn't cranky-- nap time was something nobody tried to put off when it came to it So instead, he set her down with Ratchet a block or two away, asked if he could watch her while he.... Investigated something.
"sure kid, I'm not doing much here anyways, might take the stasis nap with her."
Holoform active, Optimus speeds back to the shop, worried that maybe she wasn't there or he missed it or-
"What are you doing back here? Need something else, Ori?" It takes him an embarrassingly long time (and a bit of money(little sweets are going to be in the candy jar for MONTHS)) for him to muster up the courage to ask about it.
He comes back to a snoozing Ratchet and Sleepy Sari, just sitting near them as he fiddles with the soft, hopefully well made plush in his hands. It wasn't good, not by a long shot, his holoforms digits had plenty of holes in them from how much he'd accidentally poked himself, luckily covered by bright neon and patterned bandages. Hesitantly, he placed the plushie next to Sari, just nervous and worried, in a way, that she just wouldn't like it.
Nothing can compare to how relieved he felt when her little eyes opened, tiny slivers of red and white seeing what he made, and latching on immediately, holding onto it the same way she would hold him while being carried.
Each and every time he saw her with the toy truck, which lasted way, wayy longer than most others, his spark sang with joy.
The fact that it looked like his alt-mode was simply a plus, to her loving something he made so soso much, and he kept on learning to sew. For when it might finally tear, or break.
