i wish the best for your son, i have a 5 year old boy who gets into all kinds of stuff and in hot and humid SD there is a lot of stuff to get into. one thing to watch out for is a purple spiky plant, known in south florida as mother in laws tongue, in the DR it is all over the place, yards, balconies, border edging, you see it everyday. the sap from these long leaves causes an immediate painful welt. all a kid has to do is fall off a bike or chase a ball into some, ouch!........ to all you dog lovers out there, parasitic infections, caused by dog feces are the main reason many many beaches are off-limits to dogs. even though tides have washed away the apparent evidence, dangerous forces still lurk, it's not a like or dislike dog issue by the old ladies who are friends with the mayor's mistress. same thing holds true for lawns, even if your terrier is an angel, and you use a gold-plated scooper that belonged to the duchess of bath, it isn't healthy. a little benadryl might help with the itch symptoms, couldn't hurt, again best wishes for a speedy recovery..................
