Co sleeping and nursery?


Hi! So I'm a FTM and currently 18weeks. I have been thinking about how I wanted to do a nursery for my son, but I know that I also want him to sleep with me for awhile. Like putting a bassinet or doing the "ikea crib hack". Is it pointless to do both? Does anyone else have a nursery and also has the baby sleep with them? What are your thoughts on it?
