WATCH Mom Dresses Up Her 'Sweet PEA' Triplets in Epic DIY Halloween Costumes

Meet “Sweet PEA,” also known as Penelope, Ethan and Alejandra, the adorable 7-month-old triplets taking social media by storm with their epic DIY Halloween costumes.

After three years of infertility treatments and three rounds of IVF, new mom Ali Hynek of Highland, Utah, was so excited to finally celebrate Halloween with her new babies that one costume just wasn’t going to cut it.

“When you are longing for children for so long you can’t help but daydream of all the things you would do with them once they are here!” Hyneck told ABC News. “In my mind every holiday would be a little more memorable with a little kid we could have some fun with!”

She began brainstorming ideas for the Halloween costumes in early August, asking her Instagram followers for their input on ideas that could work in groups of three.

“They responded so positively and with so much enthusiasm to see what we would dress them up as in sets of three that I decided that I wanted to come up with a few ideas that would inspire other moms and dads to have a little fun with their own kids at a low cost,” said Hynek.

So the busy new mom paired up with her good friend, Brittany Jepson, who has a site devoted to fun DIY ideas, to come up with 10 perfect costumes for her little ones.

“My ideas were mostly ones that were simple so that any mom could do at home with a pair of PJs and a couple iron-ons,” Hynek said.

Hynek had so much fun dressing up her babies that she said Halloween is now her favorite holiday.

“Having little Penelope, Ethan and Alejandra in our life this year has revived my excitement to come up with creative ways to celebrate the holidays!” she said. “A baby dressed up in just about anything is adorable, let alone a mini superhero!”

And as for which costume was her favorite?

“I think I’d pick the ‘Celebrity Tribute’ of David Bowie, Gene Wilder and Prince because of how amazing their faces look in the photo!” she explained. “It was the first costume we dressed them up in because we thought it would be the hardest since there was face paint and wigs but they were just in awe of what was going on. I wish we would have recorded the process!”
