OKLAHOMA CITY - Daina Bradley Bruce lost her mother, son, daughter and a leg in the Oklahoma City bombing. But one year later, as others mark the deaths, she celebrates life - that of her newborn son.

Bruce gave birth to the 7-pound, 8-ounce boy yesterday, the day before the one-year anniversary of the blast that killed 168 people.

''He represents a little angel for all of them,'' said Donna Jackson, a friend of the family who was present when the baby was born at Deaconess Hospital.

Bruce and her husband, Gabe, named the baby Alize.

''He is just an absolutely beautiful little boy,'' Jackson said by telephone as the mother cradled the child in bed. ''She was just ecstatic.''

Hospital officials said the delivery went off without any problems and that both the baby and mother were doing fine.

A year ago, Bruce went to the Alfred P. Murrah Federal building to get a Social Security card for her infant son, Gabreon Bruce. Her 3-year-old girl, Peachlyn, her mother, Cheryl Hammons, and sister, Falesha, went with her.

Hammons and the children were killed in the blast and her sister was severely injured.

Bruce was buried so deep in the debris that it took 11/2 hours just to lower oxygen and a blanket to her. Doctors made the decision to amputate her leg to free her.

After a crude, 10-minute procedure, she eventually was taken out of the structure.

Bruce began to experience labor pains early yesterday, Jackson said, and 51/2 hours later, Alize was born.

''It was like a gift from heaven,'' she said.
