Hi Racehl,
Our son had a flat spot on the back of his head and it was simply from him laying on his head because he slept so much. Our pedi said to just keep him upright as much as possible instead of letting him lay down when he's awake. We bought him a Bumbo seat and let him sit in his space saver chair more often. The flat spot eventually went away (although it did take several months still).
