i dont have any experience yet but the best info ive read so far on routines is from Child and Youth Health and says that every baby is different so no one thing will work for all babies and that the easiest routine to keep is one that is flexible but centres around the feed-play-sleep routine. skipping the play during the night. but all you can do is try different things and see wat works for your bub.
good luck! hope he settles down!
