Sick with baby

Hubby had a terrible cold last weekend, fever and all so i kept baby away from him and did all the feedings and changings on my own. Now im getting sick and feel awful but he works full time so im home alone with baby during the week. I dont want to get baby sick but i feel she might already be as she sounds a little stuffy in the morning, and sneezes a little more than usual but doesn’t have a fever or snotty nose (yet). Anyone have tips or advice how to avoid baby getting sick or how to take care of them!?? Shes 14 weeks old. 😩
