What being woken up does to me

Sadie tends to wake up after she has been asleep for about 7-8 hours each night, which means she gets up around 5 to eat and then goes back to sleep until 9 or 10. Brian usually gets up to do this early morning feeding, but the other night he had to pick Jeff up at the airport and didnt get home until after midnight. So, I heard Sadie telling me she was hungry around 4:30am. I stuck the bottle in her mouth, but after a few minutes I noticed that she was not sucking and wouldn't put the whole nipple in her mouth.

And then I noticed what an unobservant mother I am at 4am.

The cap was still on the bottle.
