Hi mommys! I just had my baby at 36 weeks and I have a question

Ka

She is considered preterm.. she weighs about 5.8 lbs. I'm wondering if I should get her at least one or two premie outfits? And if you think a pack or premie diapers? I did pack 0-3 outfit for her as well as newborn diapers. She looks too small for the 0-3 month. Should I get her newborns? I think I have a few back at home, I'm currently in post partum unit right now. Thank you.
