A heartwarming video has emerged of a baby hearing his parents' voices for the first time.

The footage, captured last week in Portland, OR, USA, shows Ethan smiling when he hears his parents calling his name after he received a cochlear implant.

Ethan contracted Haemophilus during the pregnancy, a rare bacteria usually paired with meningitis and sepsis. He had to undertake a very invasive antibiotics treatment that caused his hearing to impair.

''The 4 weeks after his birth was touch and go. He was on a ventilator, hooked up with monitors, IVs, and more, fully sedated, pumped with medications and antibiotics then fluids when he became septic, in the hopes it would save his life,'' his mother wrote online.

''His chances for pulling through were very low. My husband and I were only able to see him once a day for an hour or two.''

''Finally he started getting better, making leaps and bounds in a weeks time and in February we were able to bring him home,'' she continued.

''The next couple of months were filled with specialists and doctors as he suffered from liver failure, compromised immune system, possible brain damage and was 98% deaf from antibiotics.''

''Finally in January he got the cochlear implant and got to hear for the first time,'' she added.

His story is lengthy and rare one.

First off I was told I could no longer get pregnant, we came to terms with it and enjoyed the 2 wonderful children we already had. When we discovered I was pregnant 2 years later, we were shocked and scared because we had no idea what it would bring. Luckily the pregnancy was healthy and well till the end.

I have a history of preterm labor, and the last 4 months I had gotten very sick and was losing weight, not sleeping and so on due to a severe cough that made it difficult to breath and keep food down. The OBGYN at Magnolia Clinic in Hammond LA wrote it off as a cold.

I had Ethan at 34 weeks, everything was wonderful and quick. He was making a grunting sound and we thought it was because he was premature and his lungs needed more time. Little did we know it would be something the Hammond LA hospital haven't seen in over 60 years.

They put him in the NICU to keep an eye on his oxygen, then at 2 AM I received news that brought our world upside down. "Don't panic, he's okay as of the moment but I have some news to tell you. Your son flat lined with no oxygen to the brain for 10-15 minutes. We have him hooked up to a machine that is helping him but this can cause some permanent damage." Scott went on to explain what we are needing to do from here and that there is something going on in his body.

Ethan underwent tests and found out he had contracted Haemophilus. Most likely this was contracted from me with the sickness I had for 4 months and continued till I was treated with antibiotics after the fact. Haemophilus is rare in infants and is usually fatal. It's a bacteria that goes undetected in the body as it attacks, it is usually paired with meningitis and sepsis.

The next 4 weeks was touch and go, he would flat-line often and was to unstable for tests let alone transportation to the New Orleans Children Hospital. He was on a ventilator, hooked up with monitors, IVs, and more, fully sedated, pumped with medications and antibiotics then fluids when he became septic, in the hopes it would save his life. We knew the effects the antibiotics could and most likely will have on his body. The NICU nurses were amazing and became attached as we all learned what actions we would have to take and what on earth to do with such a rare case. His chances for pulling through were very low, and when things seemed to be getting better, it would suddenly get worse.

My husband and I were only able to see him once a day for an hour or 2. It tore us apart seeing him laying there unable to hold and touch him most of the time, let alone to take him home, but we had hope and prayers.

Finally he was doing better, though we all were skeptical and waiting for the rug to be pulled out from under us again, but he showed us strength. I remember when we saw his eyes for the 1st ever! We were overfilled with joy, and then when he grabbed our finger through all the cords our hearts bursted. He continued to get strong, making leaps and bounds in a weeks time. February we were able to bring him home.

The next couple of months were filled with specialists and doctors as he suffered from liver failure, compromised immune system, possible brain damage and was 98% deaf from antibiotics. Later as we were fixing to get the surgery date for the cochlear implant for the New Orleans Children Hospital set and all was going well in August then we were flooded out and had to relocate to Beaverton OR with family. He got salmonella from the flood waters. It has been one thing after another but finally January 18th 2017 he was able to get his implant at OHSU and got to hear for the 1st time January 30th.

He is doing great, meeting milestone and showing no sign of brain damage or delay, and LOVES LIFE! And we love him. His liver has repaired it's self and all that shows from his near death experience is the scars on his head from the treatment that saved him.
