My baby just turned 4 months old and the pediatrician said that it is time to start giving him baby rice or oatmeal and for stage 1 baby foods. We decided to start with the rice but the instructions say 1 tbsp or rice and 4-5 tbsp or breast milk but when I did that it was so runny it was basically breast milk on a spoon. Should I thicken it up or follow the instructions on the package?

update: I did thicken it up a bit more but it was still very runny and he had no problems with it! It was definitely more of a trial run then a full on feeding I just thought it was very odd because it was basically milk on the spoon. Second Update: I realize some of you love your degree from Google university but my baby's pediatrician told me to start giving him baby rice so that's what I'm going to do, it's fine if you don't want to do that for your own babies but this is what I'm going to do so please if you could answer my actual question and not try to get me to not follow what the doctor who has been with my baby from birth said that would be great :)
