Carelessness and babies are two things that never, ever go together. That’s why brand new parents will do everything possible to educate themselves about child safety while their little one is still in the womb. But sadly, the most tragic and unforgettable lesson that a mom and dad can ever learn happens right after their infant take his very last breath.

This lesson comes at horrible cost, and it’s one that no one should ever have to pay. Which is why Ali and Derek Dodd want everyone to learn from their mistake. Although dad says this was no “accident,” their 11-week-old son’s passing was totally avoidable.

Earlier that morning, the boy had been his usual happy and healthy self. Derek, who works as a teacher, kissed his wife and infant son goodbye before heading off to school. In the meantime, mom Ali was preparing to drop Shepard off at an in-home daycare center. The woman who would be watching over their little boy had come highly recommended by a trusted friend.

Mom asked the daycare provider if she could bring her son’s rock’n’play, so he could be on an incline instead of laying on his back all day. But, when the childminder saw what the device looked like, she told Ali that she couldn’t let him sleep in it.
