silent radar

It's amazing to me how kids can sense when hubby is up & gone.
I mean I barely budge half the time, 430 is way to early for me.
Hubby can hit snooze 4 times, shave, dress, drink water, but on his big ol boots and walk out the door, nobody hears a thing........
Then bang silent 'daddy's gone' radar kicks in
5-530 L is up trying to get in my bed, 6-630 J is up trying to get in my bed.
Now if it's a Saturday, they don't do this, why? Because hubby is still home.
