The hard part of dealing with a vomiting child is not the actual vomit. Vomit is easy to handle. It cleans up quickly, and with the right cleaning products the smell is gone. The hardest part is seeing your child vomit, trying to comfort him as his world turns upside down and sideways. He knows that food isn't supposed to come back up, and it terrifies him. Comfort is the hardest part. The rest is cleanup.
