Answer:
If the dreamer is the parent of a young child, this dream probably represents natural parental concern for the child's health. If there is any doubt about the child's physical condition, a consultation with a medical professional is always appropriated. Otherwise, the baby in the dream is a symbol for some task, idea or project that is important to the dreamer, and that project might be subject to some threat. "Seizure" might suggest repossession or other financial problem.
