Ironically, when DS is overtired, my DH is the best at getting him to sleep. He bounces him around and loudly sings silly songs and then when DS stops in amazement to look at him DH will do something to make him laugh then will attempt to get him to sleep. I wouldnt have thought it would work but it consistently does..distraction, then something funny to get him to relax, then cuddles to sleep. If your bub is like ours it could work.
