What worked for me is having a routine. Both my boys have a routine, DS1 is 4 years old, he's in bed at 7 every night and we have no bedtime battles. DS2 is 1 and he goes to sleep at 6:30pm. They both wake between 7 and 7:30am.
So between 7pm and 7am my DH and I have time to ourselves and can relax!
I wish my time will come too
