Why do we rarely drop babies or expensive items but often drop everyday things?

I've accidentally dropped my cell phone a bunch of times, my purse, a heavy book and even a 22 Ibs bag of rice.

However I've never dropped neither my younger sister (not even when I was 10) nor my nephew that weighted 26 Ibs when he was 12 months old; more than the bag of rice. I've never dropped an large, expensive wedding cake nor fragile items that were one of a kind.

So what makes us clumsier with other items? Yet few people would drop a baby or expensive things?
