I would really welcome some advice as I am at the end of my tether. DS (3yo) has never been a great sleeper but lately he has become truly awful. This is the third night in a row that he has resolutely stayed awake until almost 10pm. We have a sensible nighttime routine (supper - bath - stories and milk in bed) but he fights against sleep until he can't fight anymore. He has recently given up daytime naps but will sleep if we are out in the car or if he is feeling poorly. I just don't know how to manage this and I would welcome some advice. Thank you in advance.
