MORRIS – The Bergin triplets just celebrated their first birthday and, although the boys go through 21 diapers and 15 bottles each day, Mom and Dad say they wouldn't trade any of it for the world.

"It's been fun, honestly. It's a lot of work, but we're loving every minute of it," said Greg Bergin, father of triplet boys who were born a year ago May 8. The family is from Morris.

The boys were the first set of triplets born at Morris Hospital in 44 years. To deliver the babies it took a nurse, pediatrician and respiratory therapist for each baby, three obstetricians, and a nurse and two anesthesiologists for the mother.

On Monday Morris Hospital held a birthday party for the boys and invited all the people that helped deliver the three boys.

As Denise Bergin carried Ryan, her teenage daughter, Kristin Terry chased after James while dad took paper streamers away from Conner to keep him from eating it – all this in a few seconds before sitting down to open presents from the hospital.

It's all in a day's work for the family.

"We work as a really good team," Greg said before running after Conner again.

Denise and Greg went through five rounds of in-vitro fertilization before becoming pregnant with the boys. James and Connor are identical twins and Ryan is the third boy. Although James and Connor look identical, and it is obvious Ryan is there brother, all three have their own personalities.

Connor was the first to start walking with James a couple weeks behind, and Ryan is starting to walk along furniture. James is the only one to have teeth yet, and Ryan seems to be the most vocal.

"We've always kept them on the same feeding schedule; same nap time and they go to bed at the same time. I think that is why it has been easier than we thought," Denise said. "They're very good babies. We're very lucky."

And having a big sister around is a huge help. Kristin is 16 – the perfect age to babysit and run errands for her parents who have their hands full.

At this time last year she was excited to meet her new brothers, but nervous about no longer being an only child, she said.

"I absolutely love it," Kristin said. "They follow me around. I love coming home from school and seeing them smile. I couldn't be happier that they're here."

The family makes it work, and when it gets tough they have two sets of grandparents close by. Both Denise and Greg's employers allowed them to adjust their schedules so one of them is home with the boys every other day. Denise works for the Will County Health Department and Greg is an attorney out of Plainfield.

The hardest part is taking the boys some place with only one parent home.

"Trying to carry three car seats is difficult," Denise said.

Many of the hospital staff that helped delivered the babies stopped into the party to say hello and see how the boys have grown.

"It's great to see them. They're so cute and so big. We don't often get to see the babies at a year old," said Kara Jirgl, Denise's nurse through the delivery.

The boys' pediatrician was present for their delivery and stopped in to say hello, even though he'll be seeing the boys the next day for their one-year appointment.

"They were my first set of triplets and I don't know if I'm ever going to (deliver triplets) again. It could be a once in a lifetime opportunity," Dr. Richard Johnson said.
