Doing grown up stuff!

Macie lives for peanut butter and jelly sandwiches or wraps. She would have them everyday for every meal if I let her. This past week though she is all about doing it herself. She gets the bread or wrap, gets the PB and J, the knife and a stool for some height and there she goes, being all grown up and making her own sandwiches. Of course being the sweetheart she is she makes one for Wade as well. What is happening here, when did she grow up so fast.
