How much does he drink? DOes he play and sleep as usual? If yes, no worries.
My bb has been 厭奶 for a very long time... now he merely drinks 4oz every meal. And he only drinks when he is asleep...
Doctors say (1) their eyes are more developed, so they become nosy... (2) their growth doesn't need as much milk as before -- that's why they drink less.
Mine used to drink 6oz, now only 4oz. So I feed him every 3 hours. He loves baana cereal more...
In fact babies cry when they are hungry... if yours follow the growth chart, no problem If u worry, feed him less but more frequently la
