Purchasing things !

Kiera • 21 , expecting my baby boy Noah October 17th , 2015 💙 he will be my first !
I'm new to this pregnancy thing . I'm only 10 weeks but I feel like I want to be very prepared when my child comes so I won't have to look for any help from others so I want to buy things in advance . do you guys know certain things I can buy ahead of time without knowing the gender ?
