Two month check up

At Cooper's two month check up he got 3 shots (1 in each leg and 1 orally).  She increased his Zantac dosage and gave him a clean bill of health!  I had several questions for her this time.  It seems like I have more questions with him (is he making enough eye contact, what is this bump on his head, does this look normal...); I guess because things are different each time.
