tired baby

So my LO is 4 months (3 months adjusted age) and he's always been a bad sleeper. He usually falls asleep for the night between 9 and 9:45 (despite trying to get him down earlier). And usually wakes up around 7am, but he wakes up tired. His naps are still all over the place timing wise, and the main problem is he rarely naps for more than one sleep cycle (35-45mins). He he's taken two unassisted (meaning not in the car or stroller) naps in his entire life. Anyone else in the same boat? I just feel so bad cause I know he's tired, he just won't sleep 😴
