I need sleep😭😩

My baby is almost a month old and he sleeps all day so he wakes up in the middle of the night and i cant keep up with him that much. People say i need to wake him up during the day and i try to but he doesn’t stay awake for much time and he falls back asleep quick. Do babies change on their own as they grow or do i have to keep trying to keep him awake during the day?
