One step forward... two steps back

A few weeks ago we took Draya's booster seat out of the basement for B to use. Draya decided that she wanted to start using it again and has been ever since.
She has also stopped using the potty before each bath and hasn't tinkled on it in weeks.
On the other hand she uses sippy cups only rarely now... instead insisting that her milk and juice come in open plastic cups. This of course makes it easier for her to practice her latest hobby... food chemistry/soup making.
