We do our best to protect our children, but what if we're not around? One little boy has been dubbed a hero after saving his 20-year-old sister from drowning.

While Morgan Smith was on the bottom step of the pool, she suddenly starting seeing black spots, according to PEOPLE. Only her little brother, 7-year-old Aiden, was around to help. The quick-thinking youngster grabbed her sister by the hair to keep her head above water, all the while frantically screaming for help.

Despite never having been taught how to help his big sister should she suffer a seizure, Aiden instinctively knew what to do. He made sure that she stayed afloat until someone heard his cries and came to help them. Without him, Smith wouldn't be here today. No one is more aware than the young woman, who proudly calls Aiden her "angel." Without Aiden being there with her at that time, the family would be facing a very different outcome.

Ever since these events unfolded, the pair have forged an unbreakable bond. If someone you love suffers from epilepsy, knowing what to do in the event of a seizure is vitally important. You should never move someone unless they are in immediate danger, such as a busy road or in front of a hot stove, according to the NHS. If they're on the ground, slip a cushion under their head to minimize damage and loosen and tight clothing around their neck to help them breathe. Once the convulsions stop, put them in the recovery position and keep talking to them until they recover.

If you've never experienced this before, it can be tricky to know when to call for help. If the seizure hasn't ended in five minutes, or it's the first time a person has had a fit, then call 911 straight away. If the person doesn't come around afterwards or has badly hurt themselves during the episode, then you should also seek medical attention.

Thankfully for Megan, she had a very switched on little brother at hand to keep her safe until help came. Well done, Aiden! Something tells us that hero title is well-deserved.
