No snacks here - not yet anyway. Like YW I have emergency snacks for when out - but that is purely because once he starts screeching, it is the only thing that keeps him quiet and enables me to finish what I was doing and get the fuck out of there before full on meltdown occurs!
We're 3 meals, 3 bottles here. But it seem's very much compacted to the end of the day? 
Milk feed in the morning, either has it in the small hours or once he is up. Breakfast an hour after bottle, or after we are up if bottle was in the night.
Then from 8.30ish he goes easily til 12/1ish til lunch is offered. Then I offer a bottle mid afternoon, usually before or after his afternoon nap, depending on time. I generally like to give it about 2.30/3.30. Then dinner at 6ish, bottle at 7.30.
So he has a big gap in the morning, but then it seems all squished in together!
