A young baby born without his skull in Florida recently celebrated his first birthday despite doctors saying he would die within days of birth.

Jaxon Emmett Buell, a true miracle baby was born with a rare brain malfunction called Microhydranencephaly, which left most of his skull and brain missing.

Doctors gave him just days to live, yet Jaxon has defied all the odds and celebrated his first birthday on August 27.

The little fighter has earned the nickname "Jaxon Strong" on social media as more than 20,000 people have shared his story.

Jax didn’t just survive until birth, he’s also defied doctors’ predictions that he would never walk, never talk, never hear and never see.

News of the child's miraculous survival was read by hundreds of thousands after his first birthday in August, though some said that Brandon and his wife Brittany were 'selfish' or should have aborted the child to avoid the pain he will suffer.

However, the father of the infant responded to the criticism in a heartfelt Facebook post Saturday night, saying his wife and his decision to keep their son was 'our choice, and only our choice'.

Brandon added that he and Brittany didn't want to 'play God'.

However, despite the couple's difficult decision, some internet commenters have questioned why they would bring Jaxon into a world where he will likely never be able to walk, talk, hear, see or know that he is hungry.

Microhydranencephaly is an extreme malformation of the brain. The condition causes the head to be smaller than normal and the scalp ridged.
