6 week old won’t let us set her down

She’s starting to wake up every time we set her down. We wait a good 20-30+ minutes till she’s in a very deep sleep and she’ll stay asleep for another 10-30 minutes but as soon as she stirs or refluxes/grunts and realizes she’s not held anymore she wakes back up crying.

We’ve tried letting her put her self to sleep but it has never worked for us. She will either start screaming bloody murder or will just stay awake the entire time between feedings and then get over tired and have an even more difficult time getting to sleep.

I go back to work in a week and 1/2 and I need sleep 😩
