First set of all-girl quintuplets born in U.S.

It's been a busy few weeks for multiples.

The first set of female quintuplets in the United States was born in Houston on April 8, and the parents are blogging about their unique experience.

Danielle Busby delivered all five girls at the Woman's Hospital of Texas via C-section at 28 weeks and two days, according to CNN affiliate KPRC.

Parents Danielle and Adam and big sister Blayke are now a family of eight. The babies are named Ava Lane, Hazel Grace, Olivia Marie, Parker Kate and Riley Paige.

"We are so thankful and blessed," said Danielle Busby, who had intrauterine insemination to get pregnant. "I honestly give all the credit to my God. I am so thankful for this wonderful hospital and team of people here. They truly all are amazing."

There hasn't been a set of female quintuplets born anywhere in the world since 1969.

Like the Busby family, Sharon and Korey Rademacher were hoping for a second child. When they found out what they were having, they decided to keep it a secret from family and friends.

That's why they didn't tell their family the gender of baby No. 2 -- or that Sharon was actually expecting not one but two girls, according to CNN affiliate WEAR.

And when everyone arrived at West Florida Hospital in Pensacola, Florida, after Sharon gave birth March 11, they recorded everyone's reactions to meeting twins Mary Ann Grace and Brianna Faith. The video was uploaded to YouTube on Saturday and has been viewed more than 700,000 times.
