I roll over & pop a nipple in her mouth.
Although, I am learning to lay for a while with my hand on her first, and see if that comforts her.
Overall, I look at it this way: I am 26 years old, and I
often do not sleep through the night. If I wake up hungry or thirsty or having to pee, I take care of my needs. I figure I owe the same respect to my child.
