Baby just did an 8 hour stretch!

My Twin A (19 weeks chronological and 12 weeks age corrected) did her last tanking up feed at 8:30 pm and took a total of 32 oz in the day before sleeping.

She hasn’t woken up till 5 am to feed! Is that normal?

Twin B usually is behind Twin A by a few weeks in milestones. She still wakes up for 2 feeds at night.

(Twin A & B are both 90th-95th percentile for height and weight and paediatrician said last week that they looked perfect though we didn’t discuss sleep).
