We had both the Arm's Reach co-sleeper next to our bed and a pack and play with bassinet (with a vibrate feature) and DD freaked the second she hit either one. They were just expensive diapering supply holders. I'll probably get both a traditional bassinet (that rocks) and the Amby Baby Hammock for the next one. I'll try (and pay) anything to give myself some options other than stomach sleeping on my chest (because in the bed next to me was just too far away for her - LOL)!
Re: bassinet recommendations?
We had a family bassinette we used, but also a Pack N Play w/bassinette attachment.
At least a pack n play has some extended utility.
