All of us siblings have allergies. I have sinusitis, my brother have fungal infection and my youngest sister who died of peripartum cardiomyopathy (from my previous post) have asthma.

Our mom is asthmatic, however, she told us that only on her last pregnancy she had this asthma due to "chalk". She was a school teacher and used chalk everyday.

My concern is, my children also have sinusitis and skin allergy.

Does it have something to do with my mom being asthmatic?

Is there any remedy or preventive measures not to pass on this allergy?
