"Well over half the women with children younger than 6 are in the labor force. This percentage has greatly affected the number of children who are cared for outside the home by someone other than a parent and the way in which caregivers and parents must interact. "

" Wright believes that in the majority of SBS cases, the caregiver or parent becomes frustrated or angry because the baby won't stop crying. This continuous crying spell leaves them feeling overwhelmed and helpless.

In fact, the parent or caregiver often starts to doubt their own abilities to care for the baby and this coupled with lack of sleep and other stressors cause them to shake the baby. Wright further adds, "In other instances, SBS occurs from an accident. That is, the caregiver or parent might have simply been playing too roughly with the baby, throwing them in the air, holding them upside down, swinging them around, or jumping up and down with them."
