Hmmm. You could use core.async, pass down a channel to children, and pass up an event each time the child is mounted. The parent would start a go-loop on initialization, count the children, and run some code when it gets the right number of child-mounting events. You could also use a general event bus for something similar, if you have one.
Other options I can think of involve passing down a callback or a local state "mounting count" atom for the children to call/inc. But really, unless you're doing something very complicated, layout is more the province of CSS. Could the Flexbox layout work here?
