Just wanted to add:
I reckon no matter how much you are "enjoying your children"...there will still be nights when bedtime is a welcomed thing.
Nights when you just can't wait to curl up on the couch with your sweet hubby.
Nights when you have budgeted a piece of chocolate into your daily calories and you don't want to share.
Or even nights when you've played your hardest and laughed until you cried...and they are still running circles around you.
And I reckon I'm okay with those kind of nights too.
