Modern Mom: An Apple A Day Didn't Work

My 3-year-old is getting ready for surgery in a couple of weeks to have her tonsils and adenoids removed. Let me rephrase that, I am getting ready for my daughter’s surgery to have her tonsils and adenoids removed. She is not getting ready because she does not know this event is going to take place. And therein lies the problem: I don’t know how or when to break the news to her. Were I to explain the procedure to her, I don’t think she would really understand. She doesn’t have a concept of time, so the fact that we’re still a couple of weeks out wouldn’t resonate. And even if she did have a grasp of the timing, why worry her for two whole weeks? On the other hand, I don’t really want to spring it on her. Shouldn’t she have the opportunity to mentally prepare, as it were? Help! What’s the best way to prepare her without stressing her out? I’m quite certain I’m stressed enough for the two of us.
