I believe the answer is...because they're there

I feed my child. I swear! I asked my 8 month old child "Why did you pull out all the tissues and eat them?" His response...a goofy grin, and another bite of tissue. I take one away, he grabs the next closest and takes a bite. After losing most of his college fund to the stock market yesterday, maybe he is trying to save us some money...Who knows? I believe the answer to Eric eating several tissues is- because they're there.
