Newborn diapers, how big of a box should I get?

I was going to just buy cases from the hospital employee store that my fiancé works at (they are huggies and are extremely discounted for the employees). But I was just looking today and they only carry size 1 and up. At 36 weeks baby girl was 5lbs 11oz and estimated to be 6.5lbs at birth. Just wondering how many new one diapers I should buy. We don’t have any of that size right now, and baby will be here a week from tomorrow!
