Bottle aversion

Karla

My son is not drinking enough milk since last. Everytime we offer milk he will start crying and refuse to even put it in his mouth. From the usual 950-1000ml we are down to 650-750ml but yoday is the worst. He would normal take 35-450 from 5am to 10am but he only took 180ml so far. Could this be bottle aversion?
