Thanks for your reply

Yes, we've tried the darkened room. The problem is that he doesn't wake the same way he does during the night. Overnight, he stirs/cries, and then practically dream-feeds, can change his nappy etc and he doesn't even open his eyes.

7pm, he is eyes wide open, wiggling to get out of his swaddle, face all lit up and just so cute it's hard not to play with him. He isn't hungry so won't feed, and there is no way to get him to sleep when he isn't tired.

This morning I didn't let him go back to sleep after his morning feed, even tho he was still tired. He fell asleep on the way back from the shops, but woke as soon as I tried to put him down. So we've had a bit of a grumpy morning. He seems to be having his long nap now, so we will see how tonight goes!
