We were all thrilled for Catelynn Lowell and husband Tyler Baltierra when they welcomed their third child, Vaeda, to the family last month.

The baby girl has brought great joy to the Teen Mom OG stars. "This baby is our rainbow after the storm," Catelynn told Us Weekly Thursday, referring to her tragic miscarriage in 2017. "We were using protection and everything. This baby just wanted to be here. It was very unexpected."

Thus far, the baby hasn't caused the usual problems that most newborns do. "She's such a good baby – very chill and easy going... so far," Cate said. She also added that her four-year-old daughter Nova "loves being a big sister."

Cate then touched on why she and Tyler named the baby girl Vaeda, rather than the original plan of naming her Tezlee. "Every time someone would say Tezlee, we would cringe! It just wasn't sitting with us like it did at first," she said.

Luckily for her, Tyler had another name in mind. "Tyler told me about the name Vaeda and I fell in love with it! It's from the movie 'My Girl,' which is a movie that Tyler showed me years ago," Cate said.

It was a good choice because fans love the name Vaeda.

Baby Vaeda will turn a month old next week.
