Sleep routine for 8 week old

So at night we have gotten baby into a routine. 10pm we bath him, change him then feed him, all lights off, quiet voices and singing to sleep. This works most nights depending if he's very unsettled. Some nights he settles to sleep at 12am and will wake up around 4am for a feed then sleeps till 7am and then up for the day.

But during the day he doesn't sleep at all often. We try settling him for naps but he's just never will settle. He probably will take 1 nap in the day for 2/3 hours but that's all.

Any tips and tricks to try and help, we already swaddle and put on calm music that he falls asleep to at night after me singing to him.
