FTM experiencing cluster feeding

For the first time. I'm assuming this is the start of what he's doing. Absolutely won't stop crying unless he's on the breast. He falls asleep on my breast... For like three minutes. But I don't dare take him off because he'll scream bloody murder.

This will be a routine? How long should I expect it to last? His time of course is starting at 11pm. ...he couldn't have picked like 2pm...

Any thing you all do to get comfortable in the meantime?
