2nd time mum here, looking to see how long you let you little one sleep at night, my girl will be one week old tomorrow and she slept for 5hrs straight last night, woke up ate a little and I pumped off the excess. I know they say you shouldn't let them for more than 4hrs, how strict are you in this? During the day I'm pretty good at waking her up at the 2hr mark to nurse l, but I feel too sleep deprived to start setting alarms to wake her up. Any and all advice from real life experience appreciated.
