"Behuz I said so"

So Halle (my niece) substitutes sounds she doesn't know with an "h". I went to nursery with her this last week at church and she wouldn't talk to any of the kids or do anything. She wanted me to hold her the whole time. I asked her why she didn't want to go play with the girls and she said, "Behuz I don't want to". I finally convinced her to have a snack with them and she sat very quietly on the bench and ate her little hot dogs (vienna sausages) and marshmallows. Then, she decided it was time to go find Grama Vik and she wasn't taking no for an answer. There was still 20 minutes left of the class so I tried to talk her into staying. She kept saying, "Wet's go Weisha" and I would try to distract her. It worked for a while and then she told me again, "Wet's go Weisha" to which I replied "Why, Halle?". "Wet's go now behuz I said so Weisha". I guess she has heard that once or twice and decided to try it out for herself. Needless to say, it worked. We left 10 minutes early to go find Grama Vik.
