I love her so much, but she starts every day with whines and moans, then ends most days with a monster tantrum. I find it so depressing. She has a lovely life and is actively and openly loved by two very present parents and a VERY patient older sister. We have tried the step, time out, removing toys, being calm, bring firm. Nothing works. Sometimes I can cope with it, other times like now I feel really bleak about it all and think 'is there something not quite right?' and 'have I caused this?' I will probably feel right as rain after some sleep, but wondered if anyone has any excellent tips or reassurance in the meantime.
