Baby’s first cold 😓

I think my baby girl is getting her first cold. She started daycare this week, so I’m sure that’s where she picked it up. She woke up stuffy this morning and is now in her crib for the night but she is coughing. It’s not waking her up (knock on wood) and I have the humidifier going, so I hope she is able to sleep. She doesn’t have a fever either. She took a 3 hour nap today, which is very unusual for her but I let her get her rest. Any tips for the early stages of a cold to make it a little easier on her? I’m a ftm and have been dreading her first cold! 😭
