We had the flu the last two weeks of 2014. Since then I have tried getting us back on our sleep schedule and nothing is working. DD is 2 and DS will be 1 on the 23rd. Anybody else have this problem? How did you correct it?

Edited to add what our schedule used to be.

Dinner at 6
Play til 8
Baths at 8:30
In bed at 9
Story and a song til 9:30

DD would usually sleep right away after this. Not anymore. I find myself fighting her to sleep til 7:30 in the morning. DS won't go to bed til midnight now...
