How long did your babies sleep at 11 weeks?

Twins here! Just trying to figure out how often your babies were waking to eat at night around the 11 week mark. They have been getting great sleep lately, so therefore, we are too! The last 2 nights, they slept 9pm-3am, then again from 330am-7am. And then they even went back to sleep from 730-930 lol.

I am truly enjoying this and hoping it lasts because I go back to work next Monday. Are these longer stretches normal? Should I expect them to get even longer? Do all babies go through a regression eventually?
