It is NOT a good idea to let your kids stay up until their father returns from a business trip at 9:30 pm.
And it's really not a good idea to let your 3-year-old drink about 8 ounces of water while he's waiting for his dad to come home.
Also, not a good idea to completely procrastinate on a presentation for work because you're obsessed with a novel that may or may not get published.
And it's a really REALLY bad idea to stay up until 2 am working on said presentation. Especially when your 3-year-old wakes up in the middle of the night because he wet the bed (can't imagine why that might have happened).
In spite of his good intentions it really was not a good idea for your husband to put the 3-year-old in footie pajamas, because when the 3-year-old inevitably wakes up at 6 am to go to the bathroom AGAIN, he screams bloody murder when he can't get the pajamas off and wakes up the entire house in the process.
So you're working on about 4 hours of sleep, the kids have 3 hours less sleep than they're used to and everyone is totally crabby and spends the morning fighting and screaming (and yes, that includes me).
Oh, and about that presentation you sent at 2 am last night, it sucks and the crazy German guy who requested it calls you at 9 am when both kids are screaming to tell you how badly it sucks and how he'd like you to re-do it.
Seriously people, learn from my mistakes.
