Should I Be Worried?

My son who a month old use to cluster feed all night is recently stopped eating a lot at night. The last four hours I’ve only probably got him to drink an ounce (I’m not sure since I’m breastfeeding). I’ve woken him up twice so far and I’ve got him to latch but for only five minutes at most both times and I try to get him to latch again but he refuses to. He’s having plenty of poopy diapers and he’s gaining a pound a week. Should I be trying harder to get this feedings in? If so how Can I wake him up? I’ve tried putting him on his back which wakes him up a bit but he still refuses to eat.
