This happened with dd a lot. She has never been interested in her early morning feedings, and for a long time I thought it was due to a late night waking - like 5am with a feed, and so she just wasn't hungry at 7. But now she is a week shy of six months, and is sleeping through from a 10:30 dream feed, and STILL doesn't want her first bottle of the morning. And the second bottle can sometimes be difficult to get her to take as well. I try really hard to get that first bottle in her, just because you're right - if I don't, the whole day is thrown off. You can try to limit the late morning feedings a little if you want, so that they will be hungrier for the first official feeding. It can be hard though, because when dd was waking early for hunger, she was REALLY hungry and wanted that whole bottle.
Unfortunately other than to try limiting the early morning feeding, I don't have any good practical advice. I have basically decided that dd is just not a breakfast kind of girl, because after noon she is a ravenous little piglett. She can't stay on a 4 hour easy - she does more like every 3 hours. But it works for us, so it's what we do
Good luck! Maybe others will have more practical suggestions.
