Hi. I appreciate your info and support on this but the problem is not just in the evening.

At the moment he is on a 4 hourly feed routine which varies a little dependent upon what time his first feed of the day is.

Today he fed well at 2am and 6.30am. I would normally feed him again at 10:30am but because I wanted to go out I tried to feed him a little earlier at 9.30am - which he refused. I attributed this refusal to him being tired so I delayed going out and put him to bed. He slept for about an hour and I tried again at 10:30 when he woke. He fed for about 5 min before refusing. I then put him in the pram and we went out where he slept from about 11:00 to 1pm, when I tried to feed him again. He refused this feed as well and cried and fussed until we got home at about 2pm when he fed reasonably well for about 15 minutes before refusing anymore. And so it goes on...

It is even more frustrating because up until 6 weeks ago he fed really well.
