Baby monitor

Hey everyone! Just wondering if it will be worth me buying a baby monitor or not, I’m kind of thinking it will be a waste of money but then I want one for later? Like I’m always going to be in the house with my baby obviously and my baby will also be sleeping in a co- sleeping bassinet so would it even be worth me getting one now or just wait until I move Bub into his/her own room (don’t know the gender as of yet) thanks 😊 if you can’t half tell this is my first baby lol
