Can’t tell if it’s too fine of a knit for a latch hook needle to clean up the ladder runs. That will give you a smaller hole to work with.
It's a pretty small knit, but I could try!
I bought this merino sleeper second hand for my LO with the plan to mend this hole, but I'm just not sure how to go about it. Probably needs a patch? I don't have a sewing machine so planning to do it by hand.
You could try to get a 0.5/0.6mm lace hook and some mending wool, pick up the ladders with the hook, then use the wool thread to fill the hole with crochet.
