desperate for some sleep

Heather
How can I get my two week old to sleep by herself in her pack n play? She slept in it for two hours last night before waking up and refusing to go back to sleep in it alone. I had her swaddled and fed and dry but she would wake up and scream whenever I put her down. 
She has RSV so I really can't risk bed sharing right now 
Is two weeks too early to let her cry herself to sleep?
