Like many physical illnesses, fevers are best treated if caught early. Especially for a toddler or a baby, being able to provide him with the right medical attention at the right time can make the difference between a speedy recovery and a few days of crying and worrying. Fever Scout is a soft flexible patch that your kid wears on his chest at all times. It continuously monitors his temperature and sends it to your smartphone; if ever it goes beyond some preset range, it’ll notify you immediately. It’ll also generate a graph of his temperature over time, letting you see what’s effective and what’s not. It’s not meant to be worn for months at a time, only a few days when necessary, and the kit comes with 10 medical grade adhesive patches. It’s $60 and available early 2016.
