Question about shoes for my little. :)

Cindy • 25 yo. FTM to a Baby girl. Grace Elena<3
I'm wondering what everyone recommends as far as purchasing shoes for babies? I know for sure not to invest in NB shoes. But what about 0-3months? Do babies usually wear shoes at this age or should I just invest in a cute pair for 0-3months and buy more shoes in 3-6 months and up instead? Any advice would be appreciated! :D 
Btw my baby is expected July 22nd. So it'll be summer time (If that makes a difference) lol
