My friend has tonsillitis & wants to see my preemie.. What do u think?

I have a preemie he was born at 32 weeks & 5 days!! He has been home for a bout a month now.. Spent 2 half weeks in the nicu& my best friend which is actually my sons aunt.. wants to see him.. well she just had tonsillitis and I heard it was contageous.. but she said she has taken her medicine and stuff and she has had it I would say a week maybe a lil more she dont get them taken out til next month! She wants to see my son but im scared he will catch it from her.. Hell im scared to go see her when BD watches my son cuz im scared im going to pass it to him (though I did have my tonsills taken out when I was 4) so im not quite sure about that! When do u think it will be fine to let her around him??!! Should I wait til she gets them taken out.. She has been my best friend of 10 yrs I hate to have her miss out on my son!
