Hi!! I just went through a phase when my baby was 4.5 that he didn't eat. After that he started eating from 6/7 ounces 5 times a day, and 2 bottles at night. He had a vaccine on Monday, and is eating only 2/3 ounces each meal. Could it be the vaccine? Could he be trying to tell me to reduce the amounts of bottles? He coincidently started solids today, but had been eating less before that.
