My 3 week old grunts and tosses when she’s been out in crib to sleep after feeding even if it’s after she actually fell asleep eating or if she burped. As soon as she’s put down by me (mother) especially she instantly wakes up. However if she sleeps in my arms or on my chest or shoulder she would be as peaceful as ever no grunting or anything. How or what can I do so she can sleep in crib at ease?
