We have night weaned, but still co-sleep. Dad sleeps in "their" room with two twin beds, they share a queen and single with me. We at this point only get dad if we have a nightwaking problem (illness). Our next plan is to have Dad get in with them and me sleep in their room, but in all cases we protect all of our sleep, Sleep deprivation has been the worst enemy.
It is just tough. Some of milestones were when they could both double nurse at night with pillows with me on my back, yes you wake up sore and touched out, but if my feet didn't touch the floor in the night I called it good.
Pushed solids and lots of drinks before bed, verbally told them the noni's would be there in the morning.
At nap time started -- you can just have "one-two" noni's. I would let them have a few sucks--to my tolerance and say "one-two" we cuddle now--that way I didn't have to say a negative. As that worked, then it worked in the middle of the night, they would latch on and I would say remember "one-two" they let go and went back to sleep. Gradually to no night latching on. Now this was a transtion, didn't happen over night, but consistencency/with love on my part/we made it to a better road.
Now Dad can run their ear to sleep, we still have some "one-two's" and one twin prefers to just go to bed with me laying with him. They will go sleep with caregivers reading or watching a vide--but they are older than some at this point dealing with the issue.
