If you want new (and who doesn't?) please donate it when your baby grows out of the stuff. Lots of poor people out there who cannot afford nice things for baby.
Worse is all the plastic junk and toys that go along with having a baby. Clean them, pass them on to friends and family or donate when your baby grows out of them.
I was born in the fifities. I had a bassinette, a rattle and a bottle.
