I have a 14 month old daughter and her temper is getting out of control. She is throwing herself down and banging her head against the floor if she doesn't get her way. I do not know where she learned this behavior from. I only have one child so I never had to deal with this from a parents point of view. My brother acted this way when he was younger. Is it hereditary? I tried to pick her up and set her on the couch when she was acting this way but that did not help. I tried to ignore thinking she is doing this for attention but that doesn't seem to work. For the most part she is an excellent child. I am a stay at home mom so most of my attention is on her. Does anyone think that is why she acts this way.  
 
This is an example of what happened today. I was making her lunch. I opened the refridgerator to get something out. She then stood in the fridge and when I asked her to move she screamed at me. I then picked her up and moved her out of the way so I could close the door. she started screaming not crying screaming and threw herself to the floor. I am worried that this is going to get worse over the years any advice is appreciated. She only reacts this way with me. What am I doing wrong?
