Sick baby?

BabyBlu🐼 • Mom of Irish twins
Has anyone's baby gotten sick yet? On thursday, my babysitter called and said that she thought her son had a cold but that i could still bring my daughter over if i wanted. I have no other babysitter options and it was kind of last min (an hour before i had to go to work) so i decided to take her anyway. Babysitter promised to keep her son (3 years old) out of my daughter's face so that she wouldnt get sick. Well looks like it didnt work 😭. Im sitting here at 5am, listening to my baby cough every few minutes and she sounds really congested, sometimes it sounds like she's having a hard time breathing. She doesnt have a fever and even with all the coughing, all she does is toss and turn and then goes back to sleep. Im wondering if i should wake her and giver her some Tylenol? She wimpers (still asleep) whenever she coughs which makes me think she's in pain but it doesnt wake her so should i just let it go until morning?
