I agree with PP - you need to see what time suits you best. Some times you may find they don't feed well at a certain time and you need to try a little earlier or later to catch a different part of the sleep cycle.
I also agree with Emma that your little one is too young to start reducing feeds. He really needs all the calories he can get at the moment and feeding him when he wants it is exactly what you should be doing. {{HUGS}} I know it's hard when you get very little sleep (believe me with 2 refluxers I know
) but give him a few weeks and the two night feeds should become one, then he will eventually not wake for a feed, but let him guide you.
