Baby refusing to be put down

I need advice. My lo was born at 34 weeks, completely healthy. At about 4 weeks she started not wanting to be placed in anything (crib, pack n play, swing, rock n sleep). It's progressingly gotten worse. She's 9 weeks now. During the day we literally can't put her down, or she'll scream bloody murder, except for 5-10minutes on her play mat. At night, my husband will hold her while she sleeps from 9pm-1am, ill feed her and then she will typically sleep in her rock n sleep for 3 hrs. So total in a 24hr period she is not being held pretty much just those 3hrs at night. I'm at a loss what to do. We try placing her down during the day, numerous times. Her ped says its bc she's a preemie, nothing we can do. I go back to work in 3 weeks and she starts daycare, who obviously can't hold her for 8hrs. She is EBF, if you're wondering. I get "she'll grow out of it" but it's been 5 wks and seems to just be getting worse. Thank you for any suggestions.
