Re: 14 month old throwing tantrums!
My youngest was a little monster for a while there. I found that I wasnt as consistent with him as I had been with the other 2. That was SO key. Once we structured his day and stuck to it consistently and rigidly, he got much better. The daily routine thing.
Also, consistency with behavior. If I told him no, the answer stays no. When you give in to a demand in order to stop a tantrum, its like rewarding bad behavior. I changed my tactics there - if he was having a tantrum, I'd pick him up and bring him to his room. Then tell him that if he wanted to be noisy and unhappy then he could just in there until he wants to be happy again. Never reward bad behavior!! Once I changed these 2 things and stuck to them consistenty, he was like a different kid.
