My yellow grafted moon cactus was growing babies before I watered it too much and it began to rot. I happened to be growing some dragonfruit cactus from seed. Are the seedlings large enough to sustain a graft of the size of the moon cacti babies in the pics? If so, do you have any suggestions besides chopping the top off and lining it up perfectly? I’m not sure how I’d attach it as they’re so tiny and delicate. Thanks for any help!

No they’re not. You’ll never get dragon fruit large enough to graft onto growing indoors. It needs full sun. Do you have a plant store near you that sells cacti? You can use other types of cactus for stock. You’ll also need to remove the rest of the dragon fruit stock from the scion if you plan to re graft it.
You can graft seedlings any time after germination, even just as [tiny cotyledons with no central stem](https://www.facebook.com/FairDinkumSeeds/posts/pfbid02JPAifdmhnc42vubyJkGqH4GcP46dobwFZaLTSccmMS5DP66MD573Gp46trowWEiMl).
You really want small mature growth with areola removed, then dehydrate the stock and soak your seedlings so when applied the stock latches on to suck out moisture.
Those ones you can use micropore tape, place pups on the tape, then use it to apply and tension it to the straightest rootstock. Even so more mature rootstock would be better as they are super likely to stall then branch once cut.
Often, home Depot has T. grandiflora. That would make a great stock. Cut the top horizontally, then cut each spine at 45° so you get a cone with a flat top. Much better long term than hylocereus.
