FTM need advice from other moms

Esmer
Since I'm moving into a new place I'm not going to have a baby shower. I'm 18 & FTM so I really don't know what I NEED NEED for my baby boy and I feel like such a bad mom for not knowing ... I already have so much nb, 0-3, and 3-6 clothes, I have a good amount of blankets for him, a play pen that comes with a bouncer &  changing table and that's pretty much it. I'll be 32 weeks on Tuesday and I know I have to start buying more stuff I just don't know what to buy? Please ladies what are some things I HAVE TO buy for him!
