All grandparents are naturally concerned about their grandchildren. A large child growing well may normally seem to have a round belly.


You mentioned a slightly enlarged spleen but did not mention an enlarged liver. Because of the slight yellow I am sure that basic labs were drawn to assess liver function. You mentioned tongue thrusting but that does not necessarily equate to an abnormally large tongue.


There a significant congenital and metabolic problems that can cause yellow color (jaundice) in a 3 month old. The problems you describe, however, may still be caused by only minor variations and over anxiety in interpreting the signs and symptoms.


Let’s hope this is the case and trust your pediatrician to complete his workup and make any appropriate referrals if he thinks it indicated.
