WELCOME to PF, dmax!
Yes, sounds like typical toddler behavior known as the "age of independence" or the "terrible twos". I don't know if it's available in the UK, but a great book that I found very helpful is <U>What To Expect the Toddler Years</U> by Arlene Eisenberg. ParentCenter.com is also a good resource for parenting, child development, behavior, etc..
