hi there! i just wanted to let you know i am going through the same thing with my 3 month old son. my 2 daughters (non cah) also had chubby cheeks, but his are the biggest. he is also chubby all over as well. 16lbs. how much does your child weigh?? his 17ohp was low as well so we did decrease his hct 2 weeks ago. i have not noticed any change and i think the cheeks are just him. he is also growing in his height. is your child??? that would definitely be  one of the symptoms of being cushy. increase in weight with no growth in height.
