My almost 7 week old....

For the last two weeks my baby will not sleep anywhere except on my chest or in my or my fiancé’s arms at night. During the day she will nap in her rock and play occasionally. This is exhausting! I don’t know why this started because I didn’t hold my baby all the time (with my first I held her 24/7) and she just won’t get comfy enough to sleep anywhere

Anyone else having this problem ?
