6-week old sleeping through the night?

Is 6-7 hours too long?? My husband and I used to set alarms every 3 hours to wake and feed but our pediatrician cleared us at her 1-month appointment that we can start letting her wake up at her own.

We put her down at 9p and she woke up on her own at 3:30a … but that means she went a bit over 7 hours between feedings.

Is this too long between feedings? She’s eating well and has enough wet diapers...
