I play Hand and Foot every other week and the four of us love using these. You get 13 cards and it is very handy to have.

Felt great until it dug into my waist while sitting causing damage to my surgical site. Now I'm in pain with and without it on.

Ex Input:
I was very happy with this DVD set (and in fact just ordered the breastfeeding DVD from the same instructor). I watched it in lieu of attending childbirth classes and do not regret that decision. I had read several books about labor and delivery, etc., and can't say that the video really contained a lot of new information but it brought the information together nicely and made me feel more prepared overall. I also appreciated the fact that the instructor did not spend a lot of time on breathing techniques and did not overly emphasize natural childbirth. Instead, she discussed the desirability of postponing medications until the labor is well underway because of the cascade effect of interventions (which seems sensible to me). But she certainly didn't try to push going natural all the way. As for the humor, it's not anywhere near as bad as some other reviews have made it out to be.

Ex Output:

Positive
