First time momma advice

Kelcie • I`m Kelcie! 20 year old mommy to an 8 month old girl.
Hey mommies! 
I'm a FTM and I'm having the hardest time trying to figure out what I should be stocking up on for the baby? I want to be fully prepared and I don't mind having too much of something and wasting the money. I know what she needs but I don't know what items I should be getting a lot of? Are there any things you never thought of when you were pregnant and wish you would've gotten before you had the baby? 
Thanks ladies!! 😊
