Girls, how do you put your babies to sleep at night? Do you rock them or do they fall asleep while feeding? I tried to make her fall asleep while feeding, but she's not going to sleep. She lies and sucks, then lets go. She's tired. On my lap, lying down, she doesn't want to sleep right away, she wants to be upright. Oh, it's new, we barely get to sleep.
