JaMichael Brown's weight of 16 pounds, one ounce, to his mother, Janet Johnson, was some four pounds more than doctors at Texas-based Good Shepherd Medical Center expected-placing him firmly at the top of the East Texas hospital's baby-weight records-and prompted an examination of state records to see if he could be the state's biggest baby.

And, as of now, he is.

JaMichael, who was taken to the Neonatal Intensive Care Unit after his birth Friday to regulate his blood sugar but is thought to be healthy, is already larger than most three month olds. Even the diapers at Good Shepherd Medical Center's nursery were too small for him, according to his mother, Janet Johnson.

I can't believe he's that big. A lot of the baby clothes we bought for him will have to be returned. They're already too small for him to wear, Johnson told FOX News. I'm happy, the proud mother added. We'll be here for a few more days, and then I'm looking forward to bringing JaMichael home and just loving on him.

JaMichael, who was delivered by a caesarian, or C-section, birth is Johnson's fourth child but first son.
