toddler 'tude

Is anyone else getting a huge attitude from their little one yet. My son will be 1 on July 12th and has recently been throwing major tantrums. Not only will he throw himself on the floor, wailing, bur he os also hittong and biting. He is not in daycare and most certainly did not learn this behavior from home. He is even hitting if we have to take a toy away, take him out of the bath, or at basically anything he doesnt want to do/like. I know the toddler years are tough, but I didnt think it would start off like this and this soon!
