Your adorable little toddler turns into a tiny monster when rage hits her. If grown ups have anger management issues, what more a tiny toddler who is barely getting used to the new world around her. She lacks self control. She may even fear her own anger. Can't get her message across. Maybe she is just upset or irritated and doesn't how else to express it. So how do you handle and angry, out of control baby or toddler?
Would yelling at her work? It may well escalate the tension and make matters worse. You can stay calm and make sure she doesn't get hurt. Don't give in to her tantrums as she may learn to use temper tantrums to get her way. Instead, stay calm but firm. Explain to her she will not get what she wants by throwing a tantrum. Tell her you will see to her only when she stops yelling. Then ignore her until she calms down.
Do take note of what sets off her tantrums. Watch the signs to prevent the tantrum from starting or from escalating when her temper starts to show.
If you know she blows up when you stop her from playing with something, then remove it. Keep temptation away from her if possible. If she hankers after something and you know she will throw a tantrum if she does not get it, distract her with something else she likes, which is safe for baby, like a favourite blanket toy or a game or some story as soon as it catches her eye.
If you know she always fights with a particular kid whenever they meet, and you are going to a gathering where both kids are present, warn her ahead of time she must not become angry. Set up some rules as to how such behaviour would be punished (for example, no television for the day) and follow up should she break the rules.
