Hi S.,
When my son was about that old, he started a pretty regular schedule. He ate breakfast, lunch and dinner, with a bottle before we laid him down. I was told that they are pretty good at knowing when they want to eat...if he's not hungry in the morning, maybe let him play and wake up, and then offer him a bottle/breakfast. Plus, if he's teething at all, that could affect his appetite too. When my son was teething, his appetite seemed to decrease. Hope this eases your worries.
