38 weeks & 3 year old with Strep

My 3 year old tested positive for Strep today 😩 Poor thing was miserable. I can't not cuddle him and help him feel better when he just wants his mommy. I'm so nervous about having the baby in the next couple days while he may still be contagious, or my husband or me catching it and then the baby getting sick 😷 Anyone been through something similar or going through something similar now? I know this is what life with 2 will be like, just hate that it's happening SO early in little brother's (possible) entrance into the world!
