"They are helping us fill my daughter's life with happy things," he said.
"That day it kind of plays over in my head pretty much every day," Mars said. "Her life expectancy, rarely do they [children] see over 2 years old. I couldn't stand there and have someone tell me that my daughter wasn’t going to be with me for as long as she should be, until I'm an old man."
"Children that have SMA, there's a quality of life you have to decide as a parent," he added. "We want her to be happy and experience the fun things. When it comes to her staying in a hospital more time than she's been out of a hospital, that’s where I draw the line."
In an effort to give baby Zailynn the happiest times of her life, her dad and the rest of the Mars family created a bucket list composed of 51 items to check off.
"Number one is to have daddy walk me down the aisle," Mars said. "Being able to walk my daughter down the aisle at her wedding is the best thing I'd ever do that I'd never be able to do."
In order to improvise for life moments such as weddings and prom, Mars said he was able to walk with Zailynn down the aisle at a friend's September wedding.
For No. 29 on the list -- go to prom and have pictures taken -- family and friends are holding a mock prom for Zailynn at the family's local church in Fairwater, Wisconsin.
Mars said his main objectives are to enjoy the time he has with Zailynn and to promote awareness for SMA.
"With my daughter's story, we want her to bring a positive impact on everybody's life," Mars said. "She a very excited baby -- happy to see anybody. If you look into her stroller, you'll definitely get a smile. She's 100 percent a daddy’s girl."
