I wouldn't entertain CC, but there is lots you can do to start helping your baby sleep.
First loose any concept that you need to stop caring or interacting with your child. Of course you do, young children/babies need to feel safe and secure to sleep.
Sort yourself out a comfy place next to the cot. Ideally a bed to lie on next to the cot but if not a comfy chair.
Feed baby, wind, place in cot. Then stay there, leaning into the cot giving as much care, attention, compassion and reassurance as your baby needs.
Of course they'll be lots of crying at first. But you stay with baby patting, stroking, tickling, shushing, singing, talking gentle and reassuringly. Whatever is needed.
Forget no attention. Give tons of attention.
Gradually overtime baby will feel more secure and safe to sleep with less and less of your attention. But it is a gradual, baby led thing
