Before I became pregnant, they were REALLY bad, sneezing, coughing all night long, conjuctivitis, siritis, exercise-induced asthma, and hives hives hives. Pregnancy
took it all away, and when I became pregnant again, baby #2 brought it all back :(
Allergens do come in through the air and through the foods we eat. Lots of people touched on managing the air quality stuff so I''ll just add that I'm trying a probiotic to help, to see if improving my GI health might help.
