TACOMA, Wash. (AP) - A Bonney Lake couple is celebrating their quadruplets' first birthday this weekend.

Lesley and Guy Culley say their kids have been relatively easy babies but that doesn't mean it's easy to take care of four babies. The quads are active and crawl everywhere and soon will be walking.

It's also been a challenge for Guy, the family's sole wage-earner, to keep up with expenses. He says the family of eight is moving to a smaller, less expensive home, to make things easier.

Their brood includes two children from previous relationships: 7-year-old Brent and 6-year-old Meg.

The family celebrated the quadruplets' first birthday a day early because more people could attend the party on a Saturday. The babies, who were born about two months early, are all healthy.
