Hi my daughter is 4 in march and lately she is completely ignoring me when I'm telling her not to do things. She drags her baby sister along the floor and when I tell her stop she acts like she can't hear me. I can say something to her 20 times and she ignores me. How can I handle this as it's making me really angry with her? I'll take her toys away, send her to her room, take treats away, but nothing works. She's the same with other adults too like her auntie and my neighbour who she knows well. she was always a lovely well behaved (most of the time) child. Is it an age thing?
