I dont know how to baby shop.

M
So yesterday SO & i were doing our xmass shopping & we went to get our niece xmass present we didnt know what to buy her, they had a lot of beautiful things but i just couldnt pick anything because i wasnt sure if it was cute enough. I am afraid that i wont know how to dress my baby when we have one. Did any of you ladies went through something similar to this? & how did you learn to baby shop?
