He joins big sister Leni, 2, and brother Henry, 1. Johan Riley Fyodor Taiwo Samuel came into the world on November 22, 2006 weighing 8 lbs., 11 oz. "Everyone had the biggest smiles on their faces once Johan arrived," Heidi, 33, told People.

And the big siblings are "so helpful," Klum says. "Leni helps us sing lullabies when Johan has trouble falling asleep."
Heidi also says that having three children under the age of 3 keeps her and Seal, 43, on their toes. "It's never boring or quiet in our home," she says, "but we are truly blessed to have three healthy children."

"We love that they will grow up close in age," she added. "This is what Seal and I have always wanted: a home filled with children's laughter."
