Play yards, bouncer chairs and stationary entertainers.
I've been starting to put my registry together and I've been researching these three product categories. I've found people who say they have such and such a product and like it, but I can't really find anything telling me what types of features are useful and stimulating vs. unsafe or superfluous. Is this the kind of product you buy because its pretty and besides general appearance they are all the same, or are there features that make one stand out from the rest? Any ideas would be much appreciated.
