I was quite baffled by that, but only for a minute. I then realized that SMB are the initials of her older cousin who graciously shares her clothes with us when they no longer fit. Many of them have been branded with her initials to avoid losing them as well. Trying not to laugh out loud at her innocence, I explained all of that to her.
She seemed to understand, at least a little, and gladly put on the mittens with her name, as well as the boots with SMB in them, because "I will just know that all of these initials are mine"
Happy Winter Everyone!
