Oliver's big thing these days vacillates between "I do it!" and "Mine to it!" He has to buckle the top buckle of his car seat. Sometimes he has to crawl (slowly and deliberately) into a chair by himself. Very often we hear the phrase, "I do it!!!" We know that if Oliver doesn't get to accomplish his self-assigned task, he will cry cry cry.
A couple of nights ago I awoke around midnight to terrible wails from Oliver, who was sobbing and screaming: "I do it!!!! I do it!!!!" in the middle of the night--inconsolably. I have no idea.
