I have a 8 months old daughter. From past few days, she goes to sleep fine at night and wakes up coughing. I usually pick her up, feed, and put back to sleep. It was only happening once past few nights, but tonight it happend multiple times. She is sleeping fine right now but i can't sleep thinking what's wrong with her. No fever, or cold symptoms. She sometimes sounds congested, but no mucus or anything. Did anyone else experience this with their baby?
