Janet Johnson and Michael Brown knew they were going to have a big baby, going as far as to tell friends and family to not buy newborn clothes for the baby shower.

 But neither one of them expected their son, JaMichael, to weigh in at an incredible 16 pounds, 1 ounce when he was born on Sunday. Doctors are still looking into whether JaMichael is the biggest baby ever born in the state of Texas.

Just how big is that? The hospital didn't have diapers big enough to fit JaMichael after he was born.

The mother, Janet Johnson, suffers from gestational diabetes which generally causes larger than usual child births. But doctors were estimating the baby would be in the 12 to 13 pound range, not the behemoth like 16 pounds, 1 ounce.

JaMichael, nicknamed Moose by nurses and doctors at Good Shepherd Medical Center in Longview, Texas, already has his parents hoping they might have a star football player on their hands.

Or maybe basketball player, Brown told NBC's Today show. I was just amazed when he came out, how big he was. I'm just proud of him ... [we're a] proud family.

In addition to weighing a little over 16 pounds, JaMichael has a length of two feet, a head measurement of 15 inches, and already sports a full head of hair. According to doctors those numbers are similar to those of a baby three to six months old, not a newborn.

It's a beautiful baby, but for health reasons we'd rather not see a baby this large, nurse Mary Beth Smith, who helped deliver the baby, told CBS News. They can have a little harder time maintaining their blood sugar.

Both JaMichael and mom are still at the hospital, but Johnson hopes to be able to take him home this week. And while she is extremely grateful that everything appears to be okay for JaMichael, she doesn't appear to be too eager to add to her four children.

That's it, no more now, she said.

According to the Guinness Book of World Records, the largest baby ever born was born in Canada in 1879 and weighed 23 pounds, 12 ounces. Sadly that baby died just 11 hours after birth.
