hi, my dd is 7 weeks old and has had a bit of a snuffly nose for the past few days and yesterday developed a cough as well. it seems to have got worse and worse i had her at the docs this morning and her chest and everything is clear and he thinks it is just a cold, but this cough is really upsetting me and her. it seems to happen after every feed and lasts for well over a minute and makes her face go bright red. i just feel so helpless and i'm terrified she's going to choke (she has sticky mucas) or stop breathing, even though i know it's irrational. has anyone else had a baby this young with a cough? what can i do to help her? thanks
