Welcome suea - and congratulations on your new baby!! I used to have, and still do have, the issues regarding winding and sleeping so you have my sympathy. I used to spend ages trying to wind my sleeping baby and I used to think, "what's the point?!" I probably try for about 5 minutes now and if there's still no burp I give up. It usually means he will wake up at done point with trapped wind but there's nothing I can do about that. One trick I do find that works well is to put DS over my shoulder and sway myself from side to side whilst patting/running DS's back. Sometimes that added sideways motion helps dislodge the trapped air.
DS slept until 04.30am so he went his usual seven hours. It had been almost 9 hours since he last fed so I was happy to put him to the breast and he had a really good feed. Normally I change his nappy at his feed to prevent it leaking between now and his next feed (he wees loads) but tonight I haven't in the hope that if I just feed and put back in his cot he will drift off. I wonder if me fiddling with him and going his nappy contributes to him being very awake during his middle of the night feed which leads him not wanting to go back to sleep for 1.5 hours 
Tonight I put him to the breast as soon as I heard him grizzle and he fed well despite being sleepy - he then went straight back in his cot without rousing. Is this that equivalent of a dream feed?
As a result he was fed and back in his cot (and asleep) within about 12 minutes which is a massive, massive, MASSIVE improvement.
I'm pretty sure that when he next wakes up he will have a very, very wet nappy that may possibly have leaked but we shall see
