HARTFORD, Conn. (WTNH) – Somewhere over the rainbow, Elizabeth Gaudino and Anna Howat, realized a dream only the love of two sisters could have endured.

The loss of twins and numerous failed attempts at in-vitro fertilization was devastating for Elizabeth and her husband Justin Guadino.

However, younger sister Anna Howat and her husband Andrew Howat gave them hope.

“As soon as she gave birth to her daughter, she said, ‘let’s do this, I’ll carry your baby.'” said Elizabeth Guadino. “Seven months to the day after she gave birth to her daughter we did the transfer and it worked the first time.”

“It was a long time coming I think,” said Anna Howat. “But after her last failed I-V transfer was when we were like, it’s alright, we’ll do it for you. It was kinda of a no brainer for us.”

The strong bond led to the birth of Charlotte Grace at Hartford Hospital, weighing six pounds seven ounces.

“It’s real now whenever I look at her and it will be even more real when we bring her home and when we can enjoy the fun moments with her,” said Justin Guadino.

“We are so thankful. We can’t express it to her what it means to us,” said Elizabeth Guadino.

Infants born to gestational carriers like Anna Howat are dubbed rainbow babies.

“A rainbow baby is a term that is used out in the community by families who’ve experienced a loss, whether it was a previous miscarriage or an infant loss shortly after birth,” Sarah Quadrato, Nurse Supervisor at Hartford Hospital. “The term is basically to give hope to a family after they’ve experienced some type of storm.”

The tight knit connection is obvious as Elizabeth Guadino recounts a trip to the store, “I’m holding her daughter who is like at the time a year and then they were like oh is this your baby? No this is her baby but that’s my baby.. laughs.”

The two families live next door to each other and are looking forward to having their children form their own special link, something the sisters obviously share.

Hartford Hospital says they are seeing more gestational carriers, mostly because state law recognizes biological parents as the legal parents at birth.
