[Q]: I'm sure the information presented in this class is good, but the presentation set my teeth on edge. Sheri thinks she is funny when she talks in a screeching voice and makes fun of new mother's foibles in her "funny stories". I cringed every time I heard her squeal as a pretended mother with a problem. If you can get past her, then I guess the DVD can give you the information and techniques you need for Lamaze. But unfortuanately Sheri spends more time talking or shrieking while trying to be amusing than just giving the information you would like to hear.
[A]: Negative


[Q]: I purchased this airbed because I wanted to sleep in the same room as my newborn. Yes, I'm one of those paranoid new moms. This bed goes above and beyond. I wanted to buy the AeroBed first because I'm one of those people who hates to buy cheaper items because they usually break or whatever. I'm pretty much a sucker for the theory that expensive = quality. However, I went with my gut and decided to try this airbed having never heard of the company before. Listen to your gut! It inflates in 3 minutes and deflates in about 3 minutes. If you want it to be more firm & allow the air to settle in better, you should leave it in there for about 7-10min. Not a big deal at all. Go do something in another room while you're inflating it. This thing can also handle a lot of weight. When I'm sleeping on the airbed, my husband comes in the room to tell me he wants to sleep in this bed too because it's so comfy. Great Buy!
[A]: Positive


[Q]: If you are looking for a great story that will really drag you into it, don't read this book. Lord help me I thought I would go crazy and only got through the first three chapters. There is not an ounce of structure to this. It's just a bunch of thoughts and "reports" of sightings of UFO's, "mothmen" and other oddities. I'm not sure if Keel intended for this to be a re-telling of things he believed really happened or if he honestly thought he was writing a novel. I can't take anymore, I give up and usually I'll read just about anything all the way through to give it a fair chance. All of these little scraps of sitings in no order whatsoever make me say... So what?!?!?!?!
[A]:
Negative
