Please help me find this movie!!

So when I was younger I remember watching a film with my family that really scared me but I don’t know what the film was! The only scenes I remember are the mother (I think) hangs herself in the kitchen. And a child under the bed has a little blade and goes to cut someone’s ankles.

If anyone knows what this is please tell me the name of it 😩 it’s been playing on my mind for so many years!!
