My 3-year-old did something similar to Hurricane Marathon when she was maybe about 2. My husband was holding her hand and walking her up the stairs to bed. She didn't want to go, and decided to do one of those toddler things where they just go limp noodle and drop to the floor (and are really hard to carry). Well, he was holding firmly to her hand, so when she did that, it dislocated her wrist. We didn't realize it until the next day (she didn't react that day, it didn't seem to cause her pain, she just started favoring it and wouldn't use it).
My 1-year-old has just started throwing tantrums. I hadn't even thought of them that way, really. But I was at the doctor's office for her checkup and she was getting tired and fussy and when the doctor had to talk to me for a long time, she started crying. So the doctor is asking me questions, etc. over the crying, and she's throwing herself on the floor. The doctor said, "And when she throws a tantrum, just ignore it." She glanced at Megan, then said, "I guess you've already figured that one out! Good job, Mom!" Heh. I wasn't really intentionally ignoring her, I just have 4 kids, I'm used to having conversations with somebody crying in the background.
