I hope that you think a little more clearer and be more concerned about the baby rather than being concerned about the consequences the caregiver might face. If you continue to rub this off your shoulder as if the baby is just sick, you soon may not have a grandbaby to take to therapy. You'll never know when the baby's caregiver will go into another rage and harm the child. I suspect that if you knew of these SBS symptoms after the babies death (I pray that this doesn't happen) then you are just as guilty as the person who committed the crime. Babies are so precious and grow into adults that make important decisions that affects people around them. You never know but this grandbaby of yours could be the one and only one that is willing to take care of you in old age. I hope you make the right decision.
