I bought the book at Destination Maternity (unfortunately for $18) and the book has been so informative and fun to read. It tells you all the know-hows for a city mom including information on great places to change a baby's diapers, baby-friendly restaurants, music-dancing-swim-gym programs, pre-school, mother's luncheons, child-friendly parks, where to have birthday parties, baby photographers and entertainers, nanny and baby-sitting services, where to shop for baby furniture, clothes, toys, what kind of baby items to get, etc. It's well organized and easy to read with useful tidbits for new moms. Since I am expecting my baby in a month, only 2/3 of the book was useful for me (since it will be a long time before I do pre-school activities and toddler-related activities).
The only problem I have with this otherwise fabulous book is that as of March 2009, a lot of the information is outdated in this fast-changing NYC environment because this 3rd edition was printed back in 2005. Just to cite a few example, there is no mention of the recent Bugaboo Chameleon or Orbit strollers; no mention of recent manufacturers and shops for baby products; even the restaurants are kind of outdated... which is not surprising since most of the information was probably collected around 2004, which was 5 years ago. So if you want very current information on baby info in NYC, I would wait until the next edition comes out (whenever that may be).
