Days vs nights

So my LO is 3 weeks today and loves sleeping during the day but fights sleep when we start our bedtime touring at around 9. During the day I can put him down in his bassinet for a nap and he’ll sleep comfortably for 2-3 hour stretches. At night I have to rock him in my arms then put him in the bassinet.m, but even then he wakes up screaming sometimes. It’s been challenging. Any tips to help flip the day and night sleep? My fiancé and I are so exhausted from the night time feedings and would love if our son went to sleep for 2-3 hour stretches at night 😊

Thanks!
