Where is the cot? Does she sleep in or or cosleep with you? Is your cot a flat pack?
I would suggest:
- making sure the cot is next to your bed. Move a chest of drawers and rearrange the room to do this, if needed.
- remove 1 side off the cot - easy to do with any flat pack cot and almost all cots (except very high end) are flat pack. Put cot mattress base on highest setting and butt it up to your bed. This is called a sidecar cot.
Then focus on getting baby to go from fully awake to fully asleep while lying in the cot. So that baby goes to sleep where she stays asleep and is not moved once asleep.
"Impossible" I can hear you say. No, it's not. Yes, it will work and no, there isn't any need for crying.
Make sure she's fed and winded. Start off with you almost lying in the cot with her. Certainly your top half - which is easily done with a sidecar cot.
Lying in your side, have your face close to baby- literally cheek to cheek. That way baby can feel your touch, hear you breathing, feel your breath, smell you - all while baby's eyes ate closed. Have one hand holding both of baby's hands, resting on babys stomach/hip area. This calms flaying limbs. Second hand over above baby's head, encircling her with closeness and protection. This hand is also on "dummy duty" - any time dummy isn't being actively sucked tap the outside of the dummy to trigger the sucking reflex. This sucking is calming and also means no crying.
Then - just wait. Don't be in any rush to move, expect the long haul. If there is any fussing tsp that dummy and maybe add a gentle "shhhhhhhhh" in her ear. It's ok to talk to her - "Mummy here, it's ok, sleep time" but keep your voice a whisper and with a slow gentle tone. Don't talk if you don't need to - keep the silence.
Watch baby's face, you see the scrunched up expression of impending fussing before anything else, so can tackle it before anything escalates. And eye contact us reassuring (and bond-forming). Watch her go to sleep, watch her eyes close. Stay close, really really close. Make calm, reassuring quiet noises and respond to any small fussing by encouraging calm - by dummy sucking and stillness (stop arms/legs kick around).
Wait until fully and completely asleep. Then wait some more. Then slowly and very gentle extract yourself to leave baby where she is to go to sleep- in her cot.
Over time (months, not days) you can gradually increase her independence by slowly reducing how close and hands-on you need to be to help her sleep.
The hands being held can be replaced by your reassuring hand lying in her chest. The encircling her can become lying next to her. Lying next to her becomes lying on bed as she's in seperate (but close by) cot... And so on.
