If only oatmeal could our problems

I couldn't wait any longer; after a month of Olivia eyeing and grabbing my food, I decided it was time for her to try some. So last weekend (at 5 months + 1 day old) we introduced oatmeal. At first, O was quite confused but by the end, she kind of caught on to the concept of eating. On the second day, she ate the entire portion and slept 8.5 hrs in a row (plus some) that same night! The next day, Olivia was not happy and giggly instead of cranky and did not scream before her naps. Amazing that oatmeal could transform my poor, tired, hungry baby.
