Allergies?

Victoria • I`m a 34 year old married woman! I`ve been with my hubby for 10 years and we have a beautiful 5 year old little girl and a 2 year old little girl! We’re TTC #3.
Does anyone else's two month old seem to have allergies?! I can't tell if it's a cold or allergies. Both her dad and me have bad allergies and the pollen count is really high right now. We don't have central air in our house because it's almost 100 years old, so we have windows open right now until we put in our window units. She's been stuffy/congested for a few days now and she sounds slightly hoarse and is coughing a bit. It doesn't sound like a wet cough and it doesn't sound like croup. But my allergies are slightly bad..my eyes are itchy and I'm a little stuffy. She doesn't have a fever at all and I keep checking. Does anyone else's kids have allergies?! What do you do for them?!
