HELP! WE'RE TRAPPED!!

Its 10pm. Drew last slept around 2:30pm. Since then he's been gassy and upset and hungry and upset and hungry... so about 15 minutes ago my beautiful and talented wife finally was able to get him to sleep in his crib. We are now both in the office (next door to nursery) and we are afraid to breath too loud. Normally he's a pretty solid sleep, but just tonight we are a bit gun-shy.
