Poppy I do hear what you are saying however there were several scenes where Bryn was being fed by bottle & Bethenny did go bra shopping. I wouldn't think you would buy new bras if you were still nursing.
I could understand the 2-3 day part BUT not long after Bryn was born didn't Bethenny take a several day trip without her daughter? Jason did say this was just for the day not overnight.
When my babies were babies I was only too thrilled to get a break & have some "me" time.
