Wrong size?!

So I have some clothes that are NB 5-8lbs and I forgot to tell my doctor to measure me and give me a guess on what weight my baby might be so I have to wait til he's due Thursday and my mom said today she think he might be bigger than 8p well I have some clothes that's been washed folded and tags long gone if my baby weights more than 8 pounds at birth we screwed lol not saying alll his clothes is nb bc it's not it's just a few are and I'll be stuck with it if he's not able to wear it!!!! But long as he's happy and healthy I'll make a way like I always do.
