You say you're going to refill your water bottle and you walk over to the copier and just stare at the machine before realizing that's not where water comes from.
How do you know you're sleep deprived ladies?

Re: You know you're sleep deprived when...
Especially since I was pumping at work. In my car.
My you try to stick a paci in your sleeping baby's mouth (or eye, or nose), because you thought you heard them crying in your sleep.
You forget to open the garage door before backing out (that one was bad. I came within an inch of hitting the door).
When you boil water for tea and then pour it into a mug, but never put the tea bag in. I've enjoyed room temp water from a mug twice this week.
When you put leftovers into the microwave and forget about them until you try heating up something else the next day.
This morning I forgot to pack milk for LO. I tried to start my car with the house key. I tried to open my house with my work key. Yesterday I stared at the stroller with the car seat in it and wondered what was missing. LO, she was in the walker, but that can't go for car rides. I asked DH what he wanted for dinner via text. He works 24 hour shift and won't be home for dinner.
When you can't find you're phone all day and then lo and behold it was safe and sound in the freezer.
