Let him pick out his own new bedding and maybe some posters to hang on the wall. Make up a new routine. When I tuck my son in at night, he likes me to sing him a couple of verses of "you are my sunshine". I then give him all of his favorite animals and blankies to snuggle up with, give him a number of hugs and kisses, blow kisses on my way out the door and that's it. It might take some time to get down the routine that will make him most comfortable, but being consistent will pay off. Make a big fuss over his room -- making it his big boy room, while his new baby sibling will have "baby stuff". Let him pick some stuff out and make his big boy choices. Start now so that he doesn't think this is all happening because of the new baby -- stress that it is because he is such a big boy and how proud of him you are for being such a big boy. Most of all - it'll take a little time, some patience and lots of consistency. Good luck. It will work!! And congrats on baby 2.
