Summer has finally come to my city and it's quite hot out. I have a very fair skinned/fair haired 17 month old and want to make sure I am taking the appropriate steps to prevent heat stroke, sun stroke, etc. I know the obvious ones...sun screen, I always put a hat on him (which, to be honest, he promptly takes off..lol), always always have lots of water and continuously offer it and keep him in the shade as much as possible. He loves to be outdoors and we spend as much time as possible doing outdoor activities and playing outside. I do try to keep us in shady areas, but he is little and loves to run so he definately winds up in the sun a fair amount. I am wondering if anyone has any other tips for avoiding these issues. Also...I know the basic symptoms to watch for, but am wondering if they can pop up several hours after exposure. For example, today we spend a good chunk of the day at a big family event we had at work. He had so much fun, but it was very hot and we were out longer then I might normally keep him outdoors at one stretch. He is fine..eating and drinking normally, full of his usual high energy antics..lol, no vomiting or lethargy or anything, but could these symptoms come up later? Is there anything else I should be watching for? Thanks so much. I am a worry wart but I figure prevention is far better then dealing with a life threatening issue like heat stroke. Any tips are very much appreciated.
