Levi Shows Off His Tiny Johnston

Levi Johnston's newborn daughter is already an expert napper -- at least judging by the hospital photos snapped after the girl was born yesterday ... and TMZ has the pics.

Levi and his girlfriend Sunny Oglesby looked like a big, happy, unmarried family at Matsu Regional Hospital in Wasilla, Alaska -- smiling and posing with their new baby Breeze Beretta moments after the parturition.

As we first reported, Breeze was born yesterday morning at 6 pounds 15 ounces.

She's Levi's second child -- after his 3-year-old son Tripp, whom he fathered with Bristol Palin.
