The women helped each other get through the tragedy, which occurred on September 16 last year. In order to deal with their grief, they started a charity initiative called Raise for Rowyn, which raises money for families who have experienced child tragedies. I really feel a lot of the time I'm just living for her and doing her work,' Cassie told KOMO. 'And I do want to make her proud.'

'We were working to get the boys loaded in the car when little 17-month-old Rowyn climbed backwards down the front porch steps in her baby blue pajamas to come see us,' the site noted. 'Her big brother did not want to go to school that day and he was crying. 'Having known one another for quite some time and our kids being in daycare together, we decided to just shut the car door and go anyway, knowing his tears would be short lived. 'We waved one last time, and the car slowly pulled forward. 'Somehow in a matter of seconds Rowyn was not where we thought she was. 'Paramedics say that Rowyn was killed instantly, and despite our desperate attempts to save her life there was nothing we could have done. 'The tragedy of September 16th has left holes and emptiness in many hearts. 'There is nothing we can do to rewind the day, but we hope to honor her memory with Raise for Rowyn.'
