Sleepless nights....

Ma

My newborn is 2 weeks old and this week she’s given up on her rocker and bassinet, but only at night. During the day, she will nap in her rocker or bassinet with no problems! But at night, she will ONLY fall asleep laying down with me in our bed and attached to my boob. I’ve been researching it and basically have come to the conclusion of it just being the “4th trimester” and hoping it goes away soon. Any suggestions or any other moms experiencing this???
