I reckon another feed would do the trick then. What time is his last feed of the day normally?

I know it is a pain to be heating bottles at 1am, but if that sees him through till say, 6pm, then at least YOU would get a lot more of a chunk of solid sleep.....

I am not sure what formula Miles is on, but most 5 month olds generally still need 5 x 240ml formula feeds per day.

(If it is any consolation, Charlie, at 11 months, still troffs through 4 x 240ml a day.....I think this is pretty standard)

My suggestion would be to feed him just before he goes to bed, then feed him again when he wakes at 1-2am, and see if that makes a difference?

Good luck...........
