Sadly - this fact is true for many parents of children under 12.
A few weeks ago the NYTimes had an article on the "family bed" syndrome. It was such a relief for me to learn that Brian and I are not the only parents on the planet dealing with musical beds at night.
Sometimes I put Ben to bed after a long day at work. We cuddle together, I sing him a song and he falls asleep...um...we fall asleep. Then at about 2am, I open my eyes and focus in on a fleet of WWI model airplanes. I drag myself into my bedroom where my husband (and dog) are fast asleep on our bed.
OUR BED....what does that even mean anymore!!! One day, Ben laughingly corrected me as he climbed beneath the covers and said "Mommy, it isn't YOUR bed, it's the FAMILY bed!"
The mere thought of going to sleep at 10:30 and experiencing eight solid hours of sleep ....well, it's just beyond the Holy Grail.
