Wearable blanket

Hi everyone I’m 35 weeks tomorrow and I’m already washing baby’s clothes and crib sheet and am planing on sterilizing bottles this week too. So as I’m doing this I’m keeping an eye out for the things that baby doesn’t have in her wardrobe... I’m a first time mom and have so many questions but the question that I have for u guys is do I need a wearable sleeping blanket for my baby? I’ve seen several but idk what to choose ive seen these do you all have any suggestions
