How many cough in a day is normal for a 2 month old baby? Yesterday my 2 month old daughter cough 6 times last night. Is it normal or need to worry?

Cough. There is no such thing as normal cough particularly for a 2 mos old baby. If it is mild use saline nose drops which keeps the nose & the throat moist & calms the cough but the couph is frequent & persistent she need to be checked by her pediatrician. .
