“When I lay my newborn down, she doesn’t just go to sleep. She fusses and cries. How do I deal with this?”
This is because she is a BABY. She is genetically programmed with survival instincts. Those instincts tell her that alone = scary danger. She has not ever been alone since she was two separate cells. To expect her to just drift off because YOU decided it was time to lay down and go to sleep is not really reasonable.
Deal with it by adjusting your expectations. Hold her. Lay with her.
I find I can sometimes start to get resentful of all the holding babies require when I am just using my arms. So get a sling. Boom! Two free hands.
“My newborn only wants to sleep in the sling. How do handle this?”
Your baby just came out of your womb. A sling is like a womb. Warm, cozy, snug, close to mom. Hell, I’d sleep in one if I could. So let baby sleep there. Anticipate that if you put her down, she’ll wake up much sooner.
There you go.
