Night feeding

It's official. My almost 3 month old is sleeping through the night. Hes started with 10-5am now he's sleeping 10-7am. I actually woke him up to feed at 7 because I checked the time and panicked, he probably would've slept longer. Do I have to worry about my milk drying up if I'm sleeping too? Will it regulate around his schedule? I still wake up a few times a night to change my pad as it is soaked and my breasts are so full in the morning that he gets a great breakfast!.

*I've never done a schedule feed. I've always fed on demand! Little man was born at 9lbs and is now 16lbs so he's definitely getting enough!*
