2-year-old girl faints every time she has a sound

Blisse Mellens's parents and sister (English) always have to speak softly in their homes to prevent the youngest child from fainting suddenly, due to her rare illness.

These parents live in constant fear because their youngest daughter can die when fainting, if there is any sudden noise in the house.

Even a sneeze can stimulate a deadly shock in your baby, so their home is almost completely silent so that the 2-year-old girl doesn't startle.

"We have to be vigilant about every noise made in the house every day," said sister Laura, 27, her mother. "If someone wakes up suddenly and she hears footsteps on the floor, she may be startled."

"I even had to leave the phone in the smallest language, because the bell also made her faint."

Blisse has two rare brain diseases such as small cerebral anomalies and ventricular cirrhosis, all affecting brain and nerve development. Apart from fainting, she could not speak or walk.

Many heavy faints can cause death, but most are transient faints that last about 20 seconds.

Her parents even had to install an alarm in their house to know if she passed out at midnight. They also have to take turns watching the baby while others sleep.

Also because she did not speak, she could not walk, so the mother could only read her feelings on her face and eyes. The doctor also said Blisse could live to adulthood but not more than 40.
