I dont set any certain time between Coltons.
He is 100% great at telling me when he want food and not a bottle (he has this whine kinda thing.. it's very distinct and he wont take a bottle when he wants food), so if he decides he's hungry I just give him some.
Breakfast is normally about 1 hour after he wakes.. so about 8-9am (about 30min after first bottle), Lunch can be between 12 and 2. And dinner is usually at 6pm.
