I am convinced he doesn't need all that milk in the night - in the day he feeds at 7.30, 11, 3, 7 and he takes about 7/8oz a time
DD sleep well - 7.30pm feed and sleep. I wake her for an 11pm feed (or am-whenever I go to bed) and then she wakes some point between 7am-8am but is never demanding of a feed straight away.
I mention this not to gloat (so please don't think that) but in relation to your daytime feeds. I cannot get my DD to lengthen the time between feeds to more than 2 1/2 hours. It is usually 2 hours through the daytime. An example day would be:
8.00am-10.30am-12.30pm-3.00pm-5.30pm-7.30pm-(woken for)11pm.
I am acutely aware that she has 7 feeds a day - of between 5oz and 7oz. This is more than the tin suggests. So I have tried lengthening the time between feeds to 3 hours. She will tolerate this through the daytime, but without fail if she has only had 6 feeds instead of her usual 7, she will always wake up somewhere around 4am and be unsettleable until she is fed.
I get the same if I try not waking her for the 11pm feed.
So, all of my waffling aside, have you tried feeding more frequently through the daytime Sherbetdip1 ? See what fitting in one or two extra feeds in the daytime (by reducing the time between feeds by maybe half an hour or an hour) does to how settled he is at nighttime.
I'd also recommend a dummy, if you've not tried.
