is a baby monitor needed? 😱

Christina
I've read somewhere recently that if you lived in a smaller place a baby monitor is not really needed...? Is this true? FTM and I don't know what to believe with anything I'm so lost 🙈 does anyone live in a smaller place and have any advice for this? (I live in a 2 bedroom apartment and can hear people talk no matter where they are in my apartment) 
Thanks in advance!!
