So many questions about bottles!
Erm... n had one at 8, 10:30 ish, 1, 3, 5 ish, last at bedtime. Sometimes a bottle at 11, and/or 2 ish.
I used to make then all up and pop then at the back of the fridge. I'd take them out when needed. When going out, Id pop them in the bag and warm then up in hot water.
I've always kept a carton of milk, in the car and one in the bag. Just incase!
Sorry to hear about the poorly/ naughty babies.
