honestly, 10 minutes is nothing in the world of CIO/modified CIO. in theory, if you're going to do it, you have to be prepared to let them cry until they fall asleep, even if it takes hours. Your husband is just going to need to suck it up - you can't really control how easy it is for him to fall back asleep. Shut the door(s) and/or turn the monitor way down/off so that you can barely hear her.
ETA: the true goal behind CIO is that a few nights will be bad, but there will be quick improvement and eventually no crying (and no waking).
