Ds is 20 months and until now has been in a sleeping bag and generally a fairly good sleeper.
I would like to switch him to a pillow and duvet, partly because I feel it's time and partly because I feel it's coming soon anyway so I'd prefer not to have to buy a winter sleeping bag if it won't get much use out of it.
I started with the pillow, it's been 5 nights now and he's not at all keen - immediately turns to the opposite end of the cot.
Put duvet on tonight wondering of that might help him stay on the pillow, it's sort of worked in that he's the right way up but he's still not actually on the pillow (I don't have a problem with this) and not under the duvet.
Have I left this too late to be doing the switch, or actually am I trying too early? I'm going to persevere but am not sure whether I should give up if it's affecting his sleep after a few nights of trying it? I will be surprised if he sleeps through tonight given his faffing with the duvet when falling asleep 
How did you approach the transition, any tips/advice?
