...Even just now he only took 1 oz He just took only 1 oz before bed after I tried for 45 mins. He prefers sleeps. Usually he ate 6 oz at bed time, and about 5 oz; 4 bottles during day time. Lately he often stops at around half way and doesn't want to continue no matter how I persuade him. He but his 2 bottom tooths about a month ago. Feeding him has been so stressful to me as it took so much effort, time consuming and wasting the formula. Is he teething again? what should I do?
