his parents were far from suspecting that this was a sign of their son's serious illness

When his child laughs, we simply think he is happy. Happy. In England, Gemma, 32, and Ed, her husband, have not thought of anything else for their little Jack.

The 2 year old baby laughed almost 17 hours a day. But not because he was happy! It was actually a worrying warning. "Jack never stopped laughing. We never had peace. He laughed even if we did not do anything funnysays his mother to the Sun. A situation that even requires moving Jack to another floor during the night because his brother could not sleep.

Continuous laughter that ends up worrying the family doctor. Gemma decides to send the boy to specialists in the nose, throat and ears. All have the same answer: nobody knows what to do with "The happy child".

"He was not happy at all, just seriously ill"

It is finally a neurologist from the Royal Bristol Hospital who triggers the alert. He pbades an MRI to Jack and his suspicions are confirmed. "My son had a hypothalamic hamartoma. He had a tumor as big as a grape in his head. All the other parts of his brain were doing well, but the part that made him laugh was under constant pressure "says Gema.

"We were so relieved that we finally understood what was wrong. But on the other hand, it was heartbreaking to know he was not happy at all, but just seriously ill. "she concludes.

After a heavy rehab, things gradually improved for the little boy, now four years old. "And not a day goes by or he smiles, and this time in good health. "
