My daughter is close to 19 months and she has been doing tantrums when she doesn't get her ways for the last three months now. Lately, it has been getting worse. She does the back arching, throwing herself on the ground, yelling at the top of her lungs tantrums. I am just reading "Making the terrible two terrific." When she has a tantrum, I let her cry for 10 minutes and then usually pick her up. The minute I pick her up, she stops crying. Is this a bad habit I am doing by picking her up? I am reading about the "tantrum room." Is this appropriate for her even though she isn't 2 year. Can I start at her age?
