It sounds like he isn't eating breakfast at home. Are you SURE they're giving him the bottle when they say?
Does the formula look thin? Are they cutting it?
What table foods does he eat? One of my own kids was a CHUNK and at 8m was eating pretty much everything in finger food form. He hated pureed food, and was on all sippy cups of BM. He ate WAY more than the same aged baby I watched at the time. He would reach OVER his tray to grab at food on her tray.
I would give him a bottle at breakfast, his fruit, cereal and some finger food/tray items.
For an AM snack, I would give him a sippy cup of water, with some finger foods.
For lunch, I would give him a bottle, his vegetables, cereal and some finger foods.
