My BB 戒夜奶 by himself at 2個月
You can try to postponse the last feeding and feed as much as your baby can eat. So that he / she is full and can sleep longer.
Like now when I back to work, I will feed him at 11:00pm for as long as he can. Then he will fall into sleep and I will wake him up next day at 7:00am for next feeding.
I have tried to feed him at 10:30pm so that I can sleep earlier. But he will wake up by himself at 5:30 am.
