I really want to know if a child has died there been unexplained things happening and it has been escalating I have two children that I have been accusing of turning on the stove but this mourning I cut the oven off to only find the oven back on.

No one here has any way of knowing if a chid (or someone) died in your house.

Check your newspaper archives or ask the neighbors.

If you own, try contacting the Real Estate Agent that sold you the house (some states have laws regarding revealing deaths in the home). If you rent, try contacting the landlord. In addition to neighbors and newspaper archives, you can check your County Clerk's Office records (deaths are recorded). All of this will help you determine if someone has died in the home. It will not, however, help you with any activity that may be going on in the home. That is another matter. Good luck with your investigation.
