Should I return my NB size onesies?

Katie
Most of the stuff I bought has been 3M or 3-6m (or even some 6-12m because it's so effing cute), but I did buy a pack of 6 onesies in the newborn size, figuring she needs something to wear right out of the womb.
I am 5'10" and my husband is 6'3", so we are big people. Babies in my family are typically 8+ pounds, so should I just forget about the newborn size?
EDIT: Thanks so much everyone! I don't know why, but my mom was like "why'd you get those??? Take them back you won't use them." But she hasn't dressed a baby for ~30 years so I figured I would check with you all ☺️ I'm gonna keep them! (And the tags and receipts)
