When little Sammisano was born in August, he weighed in at more than 16 pounds. That's more than twice an average baby weight. At five months, he now wears clothes for a two-year-old.
And that's not the only challenge. Samissano is so big, he outgrew his baby tub. And mom says the five-month-old is about to outgrow the sink too.
His family is investigating if he is the biggest baby ever born in the state of California.
