[Q]: There is no plot. What in the world did I just watch? Nothing made sense, from beginning to end. I've lost my faith in humanity after watching this...
[A]: Negative

[Q]: There's not much learning either. Sheri is incredibly condescending when she mimicks pregnant women. This video could also really use some visual aids besides Sheri holding up a poor illustration, writing lists (that she doesn't finish) on a whiteboard and the worst...her on the ground, legs spread in high-waisted khakis demonstrating childbirth.
[A]: Negative

[Q]: The fit of the fitted sheet is LOUSY - the first night we had it on the mattress, it came off. I guess Amazon sold them cheap to get rid of them.DO NOT BUY THESE!!

Negative
