Help!!!!!! How Do I Stop My Daughter from Eating the Wall and Pant from Window .

I had a kid who ate sand. I just kept repeating no firmly. He cried. Then he tried it again. I just removed him from sand box. I said sand was bad for you. He could play in sandbox if he didn't eat sand - otherwise I'd remove him. It was a very short phase. Like others have said, you just treat the same as if she was putting her hand on the stove. You don't mention how old she is - if she's too young to understand no - put something in front so she can't have access.

Check with her pediatrician to see if she has Pica.

Put a low shelf, footstool, chair, or couch in front of the window. Then if she goes to another place and is doing this I would consider other options such as moving to a house that isn't in such disrepair that she can bite a hole in the wall. That's thin sheetrock.

Do not put furniture that she might climb on in front of the window if that furniture could be tipped by her climbing. So many children are injured each year by furniture that tips over onto them. Furniture and other heavy objects (e.g., televisions) that can be toppled by a child climbing should always be anchored securely to reduce the danger to children.

Since the paint could have lead in it and be extremely deterimental to your daughter's health, I would treat this the same way I would if my child went to put their hand on a hot stove, run into the street or swim without a life vest. I would watch them like a hawk and stop them far in advance of actually doing the risky behavior.

Pick her up and move her somewhere else. If she's too young to understand the word NO then push a chair or other piece of furniture in the way so she can't get to it.

Put something on the floor in front of the window so she can't get to it. A piece of furniture, toy box, baby gate, Rubbermaid bins, etc. Also, go to the hardware store and get a lead paint test kit. I would also ask her dr. if they want to test her for lead poisoning.

Try a barrier method until she's old enough to be out of the 'put everything into their mouth' stage.
They have free form fence barrier type things for pets and toddlers that you can use.
We had something like this:

that we put around the Christmas tree until our son was about 4 yrs old.

It's either that or she can't be in that room unless there's an adult with her who will keep her from picking at the wall.
