I did think he might be to start with, but he comfortable goes without food for 4 hours in the night, so last night he was asleep at 7 and ate at 10.50 (previous feed at 6.30) then he ate at 2.30, not quiet 4 hours but i was to tired to resettle so i fed him. After 4am he is just so unsettled i can see that he is tired his eyes are closed and he does this head rubbing against the sheep skin he sleeps on to settle, he kept doing it, but just couldnt fall into a deep sleep even with my patting. I got him up at 6.30 and as its not his usual wake time he was crashing in just over an hour. I dont burp him in the night, but i will do now to see if that makes a difference at all.
