Twitch is small enough to just sit on Wheeljack's shoulder or hang of his back like a baby koala. At some point she even learn how sleep in this position so now Dad2 can work in the lab while she is taking a nap
Grimlock either picks Jawbreaker piggyback style or let him ride on his back when Grim is in his alt mode (also sometimes Swoop just... swoops down, picks JB by shoulders and flies off while Grimlock just stan there like 🦖 the frag am I suppose to do now?)
Tarantulas walks on his spider legs while carring Nightshade around, this way he can walk on uneven ground and climb while the kid can rest (Prowl is somehow balancing on his back, servo streached out in a "Onward" position. No one is brave enough to tell him it does not looks as cool as he thinks)
Hashtag is a little sad that she isn't as small as her siblings and she can't be carry around like the rest of them. Her height and weight don't not stop Starscream from still picking her up anyway when she complain about being tired. He even tried flying with her on his back (later, after they find Skyfire frozen in ice, Sky just picks her up like it's nothing, he is strong enough to far throw mechs twice as tall as Hashtag after all. In fact he is so strong, he can just let her hang of his shoulders while he is carring Starscream bridal style)
Swindle just picks Thrash by an ankle and hang him over his shoulders like a sack of dirty laundry, energon cube in the other hand, zero frag given. Thrash actually like this because now all of his energon is flowing down to his head and therefor his thinking should improve (it does not)
