Baby used baby things before pregnant?

Brenda
I'm trying to stay positive in this whole ttc thing, and I'm always at the Salvation Army, thrift shops and i see baby items and I think that's so cheap and if I ever get pregnant it would be one less thing to put on my registry  or buy (considering it is gender neutral and not beat) like swings, walkers etc, is that dumb? All it needs is a good cleaning?
