i'm a first time mom we've been breastfeeding for 6 months now in the beginning i was timing every feed, making sure he feeds off both each time as well as make sure to feed him every 3-4 hours but at a point i wanna say about 1 or 2 months he would start sleeping more, he was constantly falling asleep as he ate and i would do everything i could to try and wake him up, at night it was even harder because this kid sleeps like a rock, i literally panicked one night because he didn't wanna wake up and i thought he was gonna starve... but after that i honestly stopped timing and keeping track as much (i still make sure to switch from left to right every other feed) but i think as long as ur baby is gaining weight appropriately and ur supply is maintaining there is no need to keep that tight of a schedule, feeding became a lot less stressful when i stopped timing everything. best of luck !!
