4 week 5 days baby sleeping

My baby is 4 weeks 5 days and has been sleeping for 6-7 hour stretches the past few nights.

Put down around 8/9PM and wakes up around 2/3AM. Wakes up happy, not screaming to nurse during diaper change. Nurses then will sleep for another 2-3 hours.

Calling the pedi later today to confirm she is cleared for the stretch but any other mommas out there experiencing this? I’m loving the sleep! But want to make sure she’s OK to not feed every 3 hours at night.
