hello!
i rocked savanna to sleep till about 3 and a half months
i would wrap her then sit on the couch and rock her with my knees bent up and tap her at the same time. this worked well but when transfering her to the cot she would sometimes wake.
so then i decided to try wrapping her then placing her in the cot when she is showing tired signs. i place her dummy in her mouth too and turn her mobile on and in about 5 mins she is fast a sleep. i might need to put the dummy back in a couple times but its sooo much better that sitting or standing and rocking for like half an hour to an hour.
she just automatically turns her head to the side and puts herself to sleep.
sometimes if she isnt as sleepy she might talk herself to sleep for a bit then be out like a light

you can only try and see if it works

i have the winnie the poo mobile which has a projector light and continuously plays music for 15 mins then shuts off. its fantastic!!!
