YES!! We got back from Cuba on Jan 15th. Unfortuately, we visited the beach this vacation. Its been so long since I went to the beach when we go away, so I figured, we will go for an hour or two, sit only on chairs and then head back to the pool. We did this on the last 2 days before we left. The bites started to show up when we got home!! I just applied the afterbite to my boys and all was well.
If she sat on the sand, that would defeinitely explain the bites and where they are. They was with my sons the first few years, they would sit directly on the sand and get bite marks fromt he waist down...sometimes everywhere because they would roll around in it.
This trip, I actually got down and saw the fleas jumping around in the sand... We only sat on the chairs and my boys still got bit.
You can call telehealth if you are uneasy at the moment. But I am 99% sure, by the sounds of it, that it is sand fleas!
