My son is now 18 months and I also found What To Expect the Toddler years helpful. Another great one is The Baby Whisperer for Toddlers - this one has been a great resource for me in recognizing my son's personality and learning how to work with it when it comes to eating, sleeping, disciplining, etc. Also, The Happiest Toddler on the Block. Check them out!
Good luck and welcome to toddlerhood - SO much fun!!
