My Nephew Lakota

So in the past few nights, I have slept very little. One of my babies (nieces and nephews) have had some serious problems. I have five "kids" Dalton, Leira, Cheyenne, Montana, and Lakota. Well Lakota is 9 and he got bit by a brown recluse spider which can be really bad for a child. So I am a bit worried Our family is hearty to say the least but still. The pics are worrisome.
