1 year old screeching

[Mamalamadrama]

My 18 month (not so)DD is driving me Insane with her high pitch screeching she does A LOT.
Sometimes for no apparentent reason. Other times it's when she's at the baby gate while I am trying to cook tea or when I have nipped upstairs for a second and she is stood at the bottom baby gate. She even does it while we are in the supermarket.
It's horrible. I just tell her "no. Dont scream" I dont know how to stop it.
My mother even commented "can't you stop her screeching"
No mother. Don't you think I would if I could.
Any advice please.

My one year old does this and it's so high pitched it gives me anxiety but I think they are just experimenting and finding their voices. Someone told me the more you react the more they do it so try to ignore it or they will do it just to get your attention but I know that is easier said than done!!!

Agree with ignoring it. What do you give her to do when you're in the kitchen or popping upstairs?

@scrabbledabbl yes it gives me anxiety too. I would ignore it but it bothers everyone else in the house too.
@SiouxsieSiouxStiletto she's never on her own she has siblings to play with but if I leave the room she just screams. Cries or screeches.
