I'm so sorry to hear that your 1 week old is sick. Personally, I would take him to your ped just to make sure its not anything serious.
I know whenever my dd got sick, I bf a lot. And I can't recall if I did this when she was a newborn, but I know when she was an infant, I would take warm showers with a little eucalyptus oil rubbed on the shower walls and just hold her on me. Or I'd let the hot water run in the shower and sit in the bathroom to let the steam work its magic. The steam and the EO would helped open her up. However, I dont' know how safe that is for a newborn. maybe you can do a search on that.
Also, I hear homeopathic remedies are great for use on babies. I couldn't tell you what to use though or how to use it. Maybe you could research that.
Good luck and hang in there.
