Rant

Have any of you ever tried any allergy bedding? Karly seems to suffer from allergies year round and I wonder if it isn't partly her mattress. I have seen those mattress covers that zip on like a pillowcase that keep all of the dust mites away from the sleeper. I would love to try one of those for her mattress and her pillow but they are so darn expensive! I don't know why things like that are so expensive. It is the same with the really good carseats. They are cost prohibitive for a lot of families. How about companies with really good products figure out how to make them more affordable to the general public? M'kay?
