Early morning active sleep

My little one has always had a period of active sleep at around 5am that is incredibly noisy. I used to take her into bed and breastfeed her and she'd resettle. I'm no longer bfing now and for a while she was still settling once I brought her into bed and we'd cosleep for an hour or two until we were ready to get up. But at the moment nothing I do seems to settle her. We've tried leaving her in the cot but she is so active and makes crying sounds even though her eyes are shut and ends up waking herself up really early. I've tried bringing her into bed but she just thrashes around kicking and hitting me so I can't sleep. The only way she settles is if I sit up in bed holding her. At least that way she'll sleep til 7 but I'm still up at 5:30 unable to sleep. I tried waking her to feed her or change but then she's wide awake and won't go back to sleep until her wake window is up. Is there anything else I could try or am I just doomed to 5am starts now??
