Input (English): Passage: My second son was born just two days ago . I brought the new baby home to meet his older brother , Tom , who is only two years old . At this age Tom is interested in everything . His eyes were large as he looked over his brother , obviously not expecting him to be so small . When the baby started crying , Tom became very worried until I explained that his little brother was only hungry . Tom handed me his peanut butter sandwich to share with his new brother . Then Tom offered his glass of milk for the baby . I had to explain to Tom that small babies drink their milk from a bottle of warm milk . I asked Tom if he would like to help me warm the milk for the baby . We went into the kitchen , and I asked Tom if he could get a bottle of milk from the refrigerator . I explained to Tom that we had to warm the milk but make sure the milk was n't too hot or too cold . We checked the milk , and it was just right to feed to the baby . Question: When did he explain that the baby could drink milk? Option1: When tom saw the baby Option2: when Tom offered the glass of milk.
