Buying/setting up baby things but..

I'm 16 weeks pregnant 🤰🏻 I don't know the gender yet. But I still have gotten some things. Such as pasy, blanket, stuff animals, play pin, tub and bouncer/rocker. I even got safety things, I was just wondering when y'all mommas starting buying things and setting them up?

••The rocker/bouncer and play pin is designed for a boy and a girl.••
