How long to wait before nudging on a full

Unfortunately one month is nothing. If you can find a stated time they usually take with fulls, either in their own guidelines, or through Query Tracker or the like, give them at least that long and probably add on another few weeks, and then you can nudge.

My agent took five months to offer (and she was a same day request). Before that, with previous manuscripts I had agents take up to a year with fulls.

I know how easy it is to agonize that they didn't get it, but try to relax. 99% of the time those emails go through. Every now and then things get lost in the shuffle, but it's not the norm.

In the meantime, work on something new! It's the only way to keep yourself sane.

Gosh, the wait for fulls is super-long. About 4 months is kind of standard, for my querying experience, which is sadly extensive and protracted!

My wait times on fulls varied from 8 months and counting (at which point I had another agent) and overnight (my agent.)

Chill for another couple months, I'd say. (It would be a good idea, I think, for agents to send out a one-line "Got it!" email, just so we aren't tempted to poke, "Didja get it, didja, didja???")
