My son (11 months old) had fever. We gave him Dolo drops. He got better and he's been normal for 2 days now. Now, He's starting to cough. Coughing is minimal but his sleeping has become a big issue. Usually when he wakes up during night sleep, he searches for mom's milk and on receiving it, goes back to sleep. But now, he has trouble going back to sleep. It's clearly visible that he really wants to go back to sleep but he just can't, even with our help. Feeling helpless. Advice please.
