He did another 3 hour nap today, but took AGES to nod off. He was acting like he was not going to sleep at all, I was just thinking 'better get him up' and then he just conked out. His speech is really coming on now so I think maybe he's finding it all a bit exciting and doesn't want to waste time snoozing the day away, but he really needs it. I'll just keep putting him to bed every day and give him chance to sleep. Thanks for all the support
