Caught a cold and Nursing???

Ye
I have a one month old and I caught a cold yesterday. I'm sneezing, have a sore throat and have a stuffy nose. Dr on call at my OB's office says to take Sudafed but he wasn't really clear over the phone and basically sounded like he had somewhere better to be so is there any remodies that you moms have tried? 
Also is it ok to be around my baby? I'm a little nervous just due to the fact that I don't want to get her sick! Thank you
