Poor you! First of all I want to tell you that the charts our babies are measured on are based on the averages of formula fed babies. Formula is harder to digest than BM and therefore takes longer to get through babies system, as a result they absorb more calories and more often than not grow at a higher rate than BF infants. So don't take too much notice of charts and what the doctors say ab out them. If your LO has plenty of wet nappies then he is eating enough. As for wether to treat him as a premie, his weights seem fine. My son was 10days early and we never treated him as one so personally unless your advised otherwise I wouldn't.
Some babies are very sleepy when they nurse this is because BM contains dopamine which makes them sleepy. I know its hard in the beginning but it will get better. Try playing with his hand whilst he is nursing or talking to him in a loud voice, I found when my LO was new if I saw he was about to nod off I could wake him up again by unlatching him and sitting him up. He got cross because he wasn't getting milk anymore but it had the desired affect.
Regarding night wakings I'm afraid these might carry on for a while yet, but as you get used to being a mum and the nursing go down to once a night it will get easier. I know it easy to say but you shud try and nap when he does
Have you tried any form of meds for his wind? I'm not sure what country your in but I found gripe water was great or you could try infacol, different remedies seem to work for different babies so give a few a try if you haven't allready.
Lastly try not to get too worked up about routines, its very hard in the beginning but you'll find as he gets a little older he'll fall into the pattern with a gentle nudge. I wasn't on a great easy schedule for at least three months and then it just feel into place one day and now we are doing great. Try and relax and enjoy your son, believe me it goes fast!
