My daughter completed 6 month on 14 march and we already started to give semi solid to her after consulting to her doctor. Yesterday we gave her an apple puree for the first time. She didn't showed more interest in eating it also while eating she was making face like she will vomit. After that we stopped. But after eating it I noticed she started coughing little. It sounds like a dry cough. She is coughing in sleep also. Is there anything to worry about.
