Advice and Encouragement needing for a tired FTM

Alisha
Man breastfeeding is hard...my son never seems to be full. He constantly falls asleep on the boob so I'll put him down to get some sleep but he wakes up an hr later crying cause he is hungry. I try to keep him attached but he never seems full. He latches really well and when he doesn't we adjust and he goes on his way..trying to keep going but lack of sleep is catching up..he is a week old and actually gained weight at his appointment any encouragement and advice would be appreciated. Hoping it gets better as a ftm there is so much navigating but sleep deprivation is rough.
