Late Night Feeding

My husband does the last feeding of the night. Grace is in bed for 12 -13 hours at night; feeds around 7:30, then asleep. Mike goes in around 11:00/11:30 to "top off the tank" as he so lovingly calls it. Does she really need this feeding? We don't know... but what we do know is that she sleeps soundly until 8:00am with it... so we're not quite ready to give this last feeding up. But... tonight Mike had to call me into Grace's room to show me this! (I normally get to stay in bed during this feeding!) He thought it was too funny that she laid in her bed and fed her entire bottle to herself without ever opening her eyes!
