Visitors after baby

Love

Hi all! I had my baby boy almost 3 weeks ago & the only people that have seen him are his grandparents & my brother. He has only been to the doctor & in target wrapped up & covered in his car seat. My bestie just text me to say she'll be in town tomorrow morning & wanted to see us. I feel like this is a hard no. I know she's been vaccinated & all but I just feel like it's too early for visitors like that. Normally I think people would be okay with it, but honestly I'm scared. Am I doing too much? What would you guys do or say? I definitely don't want to offend anyone either but this is my first & only baby.
