Needing Advice!!

Ok, ladies, My baby boy will be 16 weeks tomorrow and last wed the nurse came out and weight him he was 12 lbs 3.5 ozs then I took him to the dr on friday cause I thought he was teething which the dr said he was. My concerns i am about to tell you I address them to the dr he seen as well as what i am going to come to you for concerns. Nate for the last 3 weeks as decreased in the amount of formula he has been drinking. Because he had a slight touch of relux they added ceral to his formula about a 1 month and half ago. Well he is now eating like 3 oz bottles with ceral and thats it. He eats every 3 to 4 hrs. When i seen the dr on friday they said to ceral every other bottle and see how it does well he does the same thing we dont know what to do we called the nurse and they take there time at calling back. He doesnt seem content with just the rice and formula he seems bored and doesnt want to drink it. Any suggestions also when did you start your infact out on baby food and which one did you start him or her out on. Thanks marsha
