Worried please read

So I'm 17weeks now so all the prep is starting👶🏼💕 and now I'm worried,

So basically I've had coldsore since I was about 3 year old they come and go I get them a few times a year! Disgusting I know but now I'm starting to really panic what if I pass it to my new born? Is there anything the doctors can do to help it stay away! I know how fatal they can be to new borns and children ! and it would kill me if I passed it to my baby! But what am I ment to do not hold my baby? I'm planing on breast feeding?

Any advise for a worried momma to be?
