a book sounds like a good idea. i know most current affairs shows were promoting one last year, just cant remember the name (sorry) maybe this is a reaction to having to share you and DH with his little brother. is it recent or has it being going on a long time. maybe try talking to your local child nurse clinic. they are usually a great help and can steer you in the right direction. my two boys are a year apart and share with other kids, but usually NEVER with each other and its hard coz the 3 year old has learnt a new era piercing scream.... two boys are hard. sounds like your doing all the right things and have a great deal of patience. good luck hun......
