Toddler and newborn bedtime help

I have a 2 year old, and a 5 day old. My husband us going back to work next week Nd I'm so torn on sleep between the two. Baby will nap up to 3 hours before waking to eat, and it so happens she falls asleep for her long nap and wskes right at toddlers bedtime. So we post pone until NB goes to sleep...

Is this all I can really do.. Nd then just hope nb doesn't wake and post pone bed even longer?

My toddler takes an hour (we have a routine but she has taken anywhere from 30min to 1 hour to actually fall asleep. And sometimes nb is up every hour to nurse.

Help, I loved bedtime with my toddler. Now with 2 I dread it 😭
