She won't grow out of it @November20202, you have to wean her off it. It will be hard for her, but she will have much better sleep habits as a result, so It is the right thing to do for her.
As to how to do it, there are dozens of different ways. Generally speaking the more gentle options take longer time frames to show results but involve less crying. The harsher options have much quicker time frames but involve much more crying. All options are working towards the exact same outcome though - that she goes into the cot fully awake and goes to sleep in the cot. Whichever option you choose, that is your end point. She won't "grow into" doing that without help, you have to teach her.
Some options (there are dozens more)
● Slow down the tempo of rocking very gradually over weeks/months until cuddling stationary to sleep. Then over many more weeks/months put down in the cot at a gradually less fully asleep state.
● Pick Up - Put Down. The idea of this is you put down in the cot awake, expect screaming. Comfort through the screaming whilst baby is in the cot for a set amount of time. Then pick baby up to comfort slightly (She will stay upset, you're not wanting her to fall asleep In arms). Put back down quickly and repeat over and over again.
- Gradual Withdrawal. Put baby in the cot awake and do all comforting in the cot. Making your cot a sidecar cot helps this (remove one side off cot and butt up to your bed). Cuddle as close as possible to baby. Pat, shush, hand on chest, try to help her stay still with your cuddles, face close to hers. Just keep going comforting continually until asleep.
- Cosleeping. As GW but with baby in your bed. It makes cuddling close easier As a comforting mechanism.
With all of these it doesn't involve leaving your baby to cry alone (as controlled crying does). But your baby will still cry, possibly a very lot. You have to just not get annoyed, frustrated or angry with this, plan for it and expect the distress. Stay calm, compassionate and caring throughout all her distress.
Finally, don't mix and match. Inconstancy makes everything harder. Pick a method and be very consistent about it.
