Sharing the Bed with the 1 Year Old...Not Worth It

I am never able to think clearly in the middle of the night. Ewan wakes up at 3 am, my muddled mind says "Bring him to bed with you...he will sleep and you can cuddle with him." It never works like that. Why does my mind deceive me like that?...so I can get less sleep? Or, maybe I am still dreaming. I would love to snuggle for a bit, then have the sleep fairies put him back to bed...but that would still be dreaming. In all reality, I need my mind to be reasonable and know that, yes, I might be up for 20 minutes but 20 minutes is much better than 3-4 more hours of very restless sleep. Please mind....be reasonable.
