Depends on your preference po. Ako, I won't be co sleeping my baby kasi sobrang likot matulog ng asawa ko. Natatakot ako baka madaganan or what kaya para samin, good investment ang crib/playpen.
The one I am eyeing to buy is a playpen convertible to a toddler's bed so most likely, magagamit nya yun hanggang 3 years old siya. :)
