Sleep schedule

Alexis

My baby sleeps from 11-6 or 7 every night and then eats and goes back to sleep until 10. Is this normal? I would like her to go to sleep earlier as my husband just got a promotion and needs to go to bed earlier and I am about to start working as well. How can I change her sleep schedule so that she goes to bed at 10 or 9? She’s 4 months old.
