Appetite

My 9 month old son recently had his pull-through surgery. All went well and he is happy and recovering. He just doesn’t have the appetite he had before the surgery. He used to eat 6 ounces every 3 hours. Now he’s lucky to eat 3 ounces every 3 hours. Is this common?

I noticed this myself , my son’s pull through was done almost two months ago and he too, does not seem to have the appetite he did before. He still eats pretty good, but not as often or as much at a time. He has a checkup on monday and I will ask if this is considered ‘normal’ or not. I have noticed he eats better in the morning than later in the day.
