Instead of co-sleeping, using a moses basket might be a decent option. They are very useful, does not take up much space and can be moved around easily.

Mother charged with homicide in infant co-sleeping death
 
Death of 6-day-old baby was third co-sleeping fatality in her family
 
A Milwaukee child-care worker who police say was too drunk to remember putting her infant daughter to sleep on a couch was charged Tuesday with killing the 6-day-old baby.
 
Rose Prescott, 30, told police it was possible she fell asleep on the couch with her daughter, Ceianna Buchanan, according to a criminal complaint charging Prescott with second-degree reckless homicide.
 
Ceianna's alleged homicide on March 8 was the third co-sleeping death in her immediate family.
 
Prescott's 2-month-old daughter, Brianna Buchanan-Prescott, died while sleeping with Prescott on April 17, 2008.
 
Ceianna and Brianna's 5-month-old half-sister, Cierra Buchanan, died while co-sleeping with Cierra's grandmother in 1993.
