Is it ok for my 10 week old baby to be sleeping this long through the night without feed?

He has his bath, bottle story bewteen 7-8pm and is in his basket in his big cot by 8pm. He settles himself into a full sleep. I then dream feed him at around 11pm. (give or take). He then goes without a feed until 7am. He may wake if he gets congested (i then use saline spray and he goes straight back to sleep). He then wakes sometimes at 5am - should I feed him then? As at the moment I am giving him back his dummy (pacifier) which he then falls straight back to sleep until he is REALLY waking for a feed. What do you think? Shoud I feed him at 5am or keep leaving him to sleep through till 7am? He seems fine all day - he doesnt get more hungry.
