C.K.
I have really enjoyed the "Toughpoints" book by T. Berry Brazelton, MD. He gives great advice about health, safety, potty training, discipline and other issues.
You should also visit www.parentingtools.org. There you will find a LOT of useful parenting information written by Dr. Brad Schwall, a local counselor here in Dallas. He also has an e-zine you can subscribe to.
Good Luck
