Well... You have a number of options!!
1:,Go with it, don't get stressed and make sure you sleep when he sleeps!!! Dont pressure yourself to get things done, do those when he is awake with him in a sling or in a baby seat. Be an attached partnership and relax!
2: Make small changes: Try to remove the link between feeding and sleeping so swap bath and bottle around at bed time and try to put him down in his cot during the day, even if it means you sitting beside his cot with your hand on him while he sleeps. If it's only 30 minutes, that's OK, get him back into his cot 1.5 hours after he wakes.
Whatever you try, stick with it for three days minimum and write down what happens so you can see improvements / patterns.
If bath and bed is somewhere around 7/8 and he wakes after 30 minutes, get him up, pop him in a sling while you do your stuff and put him back to bed at 10 after another feed, then go to bed yourself.
3: Find a routine you think might work and attempt to implement it, EASY: Eat, activity, sleep, you. The baby whisperer, and attempt to stick to 3 hourly cycles.
Things will change with the introduction of food which is not far off but don't expect miracles, some babies need more help than others.
