Bedtime Wars

Yes, my 3 year old is still awake (10 PM) and it has turned into an all out war. She is wide awake because my husband decided to take a nap with her today. "Oh she was just so exhausted when you went to run errands," he said. Which really translates into, "I partied too hard at the lake and so I needed to take a nap. The only way I could take a nap is if my sweet little daughter slept with me." Well now, I am paying the price. We have gone to the bathroom twice, gotten water twice, crawled out of bed about 10 times. What next? If only my children had on/off switches. Maybe I will invent that. Is it ethical?
