Cough. Girl 2.7, has croup, coughs for a week, takes Sinecod, clacid. There is a child in the house who is 1.2 years old, it's not possible to separate them, therefore the question 1-how contagious is the child with croup 2-what can be taken from medications for the sick girl to ease the condition and to the baby for prevention. Thank you.
