Getting a cold

So I’m pretty sure I’m getting a cold 😞😭. My throat is starting to get sore and I’m having a bad headache which are usually my tells for a cold beginning. I’m curious how people have dealt with having a cold while taking care of a newborn? I plan on getting some masks but cannot find any in store so I’m going to have to order some on Amazon so I don’t have any available right now. I’m really afraid of getting my LO sick. My husband is available for help but I am breastfeeding. I am getting some medicine too that I looked up to be safe for breastfeeding. Any advice for taking care of my baby? He will be a month tomorrow so I really want to make sure he’s okay.
