Any suggestions????

I am in search of some Parenting books to help me through the next year :-) I need some piece of mind and some good solid advice that I can reference when it comes to several things...the major one being sleep habits. I have talked to a lot of people and have gotten a lot of good advice....now I am looking for a good book or two so that I can have a reference on hand. Does anyone have any suggestions??? There are soooo many books on the market and I really don't want to blow money on a "bad" book. Please share any of your suggestions with me!!!! Thanks everyone!!!!
