My 4 mo is draining the life and soul out of me! she cries all day long , is never happy , I can't leave the room, I can't put her down, I have to stand up rocking her to keep her from crying, no one else can settle her, I'm exhausted. She goes to bed well at night but the days are horrendous. She sleeps for half an hour at a time and is so overtired and naggy. I want to get her to nap in her bed now and self settle but how? She does at night. I'm so stressed and hate the days . Does anyone have any advice x
