4 week old sleeping

Cara
Hi FTM here. My 4 week old likes to sleep in the day for about 5 hours at a time. He seems to sleep deeper and longer in the day rather than the night. Any ideas on how to reverse this or help / guidance. We are currently waking him in the day every 4 hours to feed and then at night do a little dream feed / top up at 11 or 12 but he still wakes for a feed at 3 or 4 then is wide awake and takes on average 2 hours to settle back down. Any help would be great as OH goes back to work Monday and I'm worried about his sleep at night too. Thank you xx
