Dr Phil Kieran: How do I recognise signs of over-heating in my kids?

We’re heading to Portugal on holidays next month with our three-year-old and six-month-old children. We’ve been there before, and there’s usually an onshore breeze, and shaded areas are easy to find. However, given the summer that’s in it. I’m starting to worry about the possibility of heat stroke and dehydration. How can I recognise the signs, and what should I pack to keep them safe?

Keeping children safe in hot weather isn’t usually too much of an issue in Ireland, but going to hot countries is a bit different.
