Thanks everyone for the replies! Sorry, have only just logged on again!
We went ahead and started the DF, so now he's fed at 10-10.30pm and then normally wakes himself again at 2-3am so only doing one night feed which is great.
Sometimes he is so hungry at 5pm so needs fed bfore his bath and sometimes instead wants more than his 6oz at bedtime so we have to give him 8oz, which then plays a bit of havoc with the dream feed but otherwise, it's working great so far.
With regards to his wind, we have just changed him onto the MAM anti-colic bottles and so far the last 24hrs have been much better. We might just be having a few good days, but fingers crossed he remains the same calm baby we have seen today!
