hello- sorry to hear about your trouble i am the same with my 3 year old, he use to go to bed about 10, then slowly it was getting earlier and earlier, now he is asleep by 9 and sometimes sooner, i would put his favourite film on (dvd normally0 bob the builder) and because the dvd kept replaying over and over again he felt bored and went to sleep, syaing this tho he will fall asleep where ever the dvd is being played than my partner would put him in his bed- i would try putting a fiml on that he likes in his bedroom and see how that goes, even sitting with him for a while may help!
