Is his bed warm enough and comfortable? Molly was getting up alot until recently, until she told us her mattress was uncomfortable, we covered it in lots of blankets so it's a bit better. Daragh got a new pillow, so we can encourage him to lie down on his "choo choo pillow" after his tickles, I've been meaning to make a nice BV one though.
I read somewhere about making a bedtime book -take photos of Ryan at all the stages of his bedtime routine - supper, jammies on, reading his book, and finally, him alseep in his bed. Print out and make into a "bedtime book", mounting on cardboard if you need to. You could also add a photo of what you and your OH might do after he is asleep (sitting on the sofa reading or something), so he doesn't feel he's missing out. At the end you could write in a song or poem that you normally sing/say at bedtime, if you do this. Do things the order that they happen in the book and eventually he should be more reassured going to bed. Whatever you decide to do, be consistent, he could just be at the age where he wants to play a bit at bedtime and finding out what he can get away with. Good luck
