Standing in Crib=Screaming

bunsee23

DD just started pulling up consistently and now does the typical "Help! I'm standing and I can't get down!" routine.  I've been putting her down drowsy and then coming in at intervals to lay her back down and pat her back to calm her.  She calms down almost immediately, but then as soon as I leave she gets ramped up and pulls up again.

We've used Ferber in the past, but this is a whole new level of screaming.  I know consistency and patience is what wins the race, but how long did this phase last for you guys?  Neither one of us is very happy (or rested) at this point.
