The first thing I try when my DD does that is putting her in the sling and taking her outside for a little walk down the street or in the yard. It seems like the white noise of the breeze in the trees and the fresh air soothes her, or maybe the change of scenery distracts her. I don't know but it usually works. If not I try a few other things before I give in to medicating her (unless it's acutely obvious she's in pain, then that's first.)
have you tried rocking her in a dark or dimly lit room with either white noise or soft music (lots of babies like classical music)? Even just singing to her or telling her a story--that helps us sometimes.
a bath will distract her sometimes, too. this helps a lot if you think it's gassy tummy; especially if you can get into the tub with her and let her move around in deeper water.
If you need more ideas PM me. My DD is also 7 mos, but I also have 2 older DD's. :)
