Luis Manuel, who was born earlier this year at a healthy and normal weight of 7lbs 11oz, now weighs 4st 10lbs – whilst the average baby boy in American weighs around 20lbs.
Doctors have told his parents, Isabel Pantoja and Mario Gonzalez, that he may have Prader-Willi Syndrome – the same condition as Katie Price’s eldest son Harvey.
Isabel and Mario have begun a fundraising appeal to try and pay for his medical treatment if Luis does in fact have the syndrome, as he would need a series of hormone injections – each one costing roughly around £404 in GBP.
Isabel said: “After only one month we noticed that clothes did not fit him and we had to dress him in clothes for a one-year-old, and even a two-year-old.
“We saw our baby gain weight so fast. Sometimes, he could not sleep because he felt like he was suffocating due to his weight.”
Mario added: “In some cases, kids have died because of a heart attack due to being so overweight.”
Katie Price’s son Harvey is now 15-years-old, and she gave birth to him when she was just 24.
Despite the difficult challenges, Katie always gushes over her eldest lad, posting photos of him on her Instagram and saying how proud she is of him.
In January, one of her posts was met with praise from her fans for being so inspiring to other parents of disabled children.
She wrote: “The love I have for this boy, my baby boy Harvey is something I can’t even put into words he is my life my world❤️ anybody out there who has a child family or friend with any kind of disability NEVER give up and be positive love and support as there is a light at the end of the tunnel.
“Harvey has proved this and more ❤️❤️ and if your the carer or parent 👏👏👏👏👏 respect to you too as I know the challenges it brings 😘😘😘😘❤️.”
