Query: Perfectly good product - only problem is, baby won't sleep in it!

This is a well-designed and constructed co-sleeper, and in principal a brilliant idea. The only problem is, my almost two-week-old baby absolutely refuses to sleep in it. We're keeping it for now and trying to introduce him to it a little at a time, but in the meantime are finding much better success with the much cheaper Fisher Price Rock n Play sleeper. This may yet come in handy as he grows, but so far, it's just serving as an over-priced changing table. Better luck to others!
