Common cold?

So my husband is sick. He has severe nasal congestion and sore throat (typical man cold). So I currently am taking care of two babies. Anyway, I put my 2 month old down for bed tonight and noticed she sounded a bit congested. Not horribly, just when she took a deep breath I could hear some mucus and this was followed by a short dry cough. This happened a few times but didn't seem to really upset her. I used the bulb syringe to clear anything out, but I'm just so scared of her getting sick. I'm a FTM. I know this builds up their immunity, but I just think she's so young still, so I'm worried. Anyone else ever experienced this? Her 2 month check up is in a week so hopefully this is just nothing and I'll just have to focus on worrying about her shots. 😣
