Toddler (17mth) has persistent cough, and childcare is complaining

Dear all parents, my son (17 mth) is having his 4th cold for the year, and his cough hasnt really go away since the year started. The childcare centre is complaining about his cough and advising us to keep him at home, but we are also burning our leaves (like no tomorrow) to take care of him at home. It becomes a struggle between sending him to childcare and work without alternative help. Anyone with similar problems?
